The specific embodiment
Below, adopt accompanying drawing that embodiments of the present invention and embodiment are described.In addition, in the following drawings,, do not repeat its explanation to the identical symbol of same or analogous part mark.
(embodiment 1)
Fig. 1 is the side schematic view of the embodiment 1 of expression shuttlecock of the present invention.Fig. 2 is the partial cutaway schematic of the converged fixed portion of expression shuttlecock shown in Figure 1.The embodiment 1 that sees figures.1.and.2 to shuttlecock of the present invention describes.
See figures.1.and.2, shuttlecock 1 of the present invention is made of with artificial feather 3 with the shuttlecock that Duo Gen is connected with the flat surfaces of base body 2 hemispheric base body 2, also is formed with the converged fixed portion 41 of the stacked state that is used to keep many artificial feathers.Base body 2 is for example formed by cork.In addition, many (for example 16) artificial feather 3 connects into circular on the flat surfaces of base body 2.As can be known, many artificial feathers 3 are configured to more away from base body 2 from Fig. 1 and Fig. 2, interval each other big more (more away from base body 2, the internal diameter of the cylindrical portion that is formed by many artificial feathers 3 is big more).In addition, the pinna rachis portion 8 (with reference to Figure 11) of many artificial feathers 3 by cotton thread such to knit line fixed to one another.The flat shape of converged fixed portion 41 is oval, forms by adopting heat sealing machine etc. to make stacked feather main part 5 partial meltings and solidify.That is to say, in converged fixed portion 41, thereby become affixed each other state by the material partial melting that constitutes feather main part 5 is solidified.In addition, the flat shape of converged fixed portion 41 can be made arbitrary shape as described later.
Like this, just can suppress because of the stacked state change of artificial feather 3 or the flying quality variation of artificial feather 3 distortion causing shuttlecock 1.In addition, in Fig. 8 and shuttlecock 1 shown in Figure 2, owing in its manufacturing process, do not need to implement in advance binding agent etc. is disposed at surperficial such operation of feather main part 5, so can further simplify manufacturing process.
Fig. 3 is the partial cutaway schematic of variation of the embodiment 1 of expression shuttlecock of the present invention illustrated in figures 1 and 2.With reference to Fig. 3 the variation of the embodiment 1 of shuttlecock of the present invention is described.
Shuttlecock 1 shown in Figure 3 consists essentially of the structure identical with shuttlecock illustrated in figures 1 and 21, but the structure of converged fixed portion 41 is different with manufacture method.Promptly, in shuttlecock shown in Figure 31, become the state that between the stacked feather main part 5 of converged fixed portion 41, disposes stiffener 43.This stiffener 43 is for example by being disposed at resin sheets such as polypropylene the laminated section of feather main part 5, and by with 5 heating of feather main part with solidify and form, is the member that converged fixed portion 41 is strengthened.For example, as stiffener 43, can adopt the resin sheet of polypropylene system, the quadrangle that length and width are 4mm, the member that thickness is 200 μ m etc.By disposing this stiffener 43, thereby can improve the intensity of converged fixed portion 41.Consequently, can improve the durability of shuttlecock 1.
As above-mentioned stiffener 43, can adopt any resin, but also can adopt the film etc. of the system of polypropylene (PP) for example.This film is clipped between the stacked feather main part 5 in advance, this part is heated, thereby can make feather main part 5 and polypropylene screen welding as stiffener 43 by adopting heat sealing machine etc.
As this stiffener 43, be and the different material of material that constitutes feather main part 5, but comparatively it is desirable to, adopt fusing point than the low material of material that constitutes this feather main part 5.Like this, then can form converged fixed portion 41 with the state of the heat that puts on converged fixed portion 41 lessly.At this moment, constitute the not fusion fully of material of feather main part 5 itself, thereby form converged fixed portion 41 by making stiffener 43 fusions and solidifying again.
Formation method as this converged fixed portion 41 for example can adopt method as described below.Promptly, as stiffener 43, prepare the film (for example tetragonal film of 4mm * 4mm degree size) of prescribed level, and this film rested on the assigned position of feather main part 5 temporarily.This interim stop for example can be adopted binding agent, bonding agent of minute quantity etc.In addition, adopt hand ultrasonic fusing machine etc., the laminated section of feather main part 5, stiffener 43 and other feather main part 5 these three-deckers is pushed heating.Like this, can form converged fixed portion 41.
In addition, if when for example adopting above-mentioned polypropylene screen, the quality of this stiffener 43 is the such utmost point light weight of about 0.04g.Therefore, this stiffener 43 can bring influence to the mass balance of shuttlecock hardly.
Fig. 4 is the side schematic view of another variation of the embodiment 1 of expression shuttlecock of the present invention illustrated in figures 1 and 2.Fig. 5 is the schematic top plan view of shuttlecock shown in Figure 4.With reference to Fig. 4 and Fig. 5 another variation of the embodiment 1 of shuttlecock of the present invention is described.
Fig. 4 and shuttlecock 1 shown in Figure 5 consist essentially of the structure identical with shuttlecock illustrated in figures 1 and 21, but have also disposed interior lines 17 except converged fixed portion 41, and the feather portion that these interior lines 17 are used to prevent artificial feather 3 is crooked (curling) to the inside.
Interior lines 17 be looped around artificial feather 3 the axle around.In addition, interior lines 17 are configured to arrive from the interior all sides that are arranged in many circular artificial feathers 3 axle of adjacent other artificial feather 3, and successively around around this.If as mentioned above, as can be known, interior lines 17 are along the interior all side configurations that are arranged in circular artificial feather 3 from Fig. 4 and Fig. 5.Therefore, when shuttlecock 1 uses, can suppress all sides of feather main part (the interior lines 17 place sides) bending of artificial feather 3 inwardly.Consequently, can suppress the generation of the such problem of the very big change of characteristics such as air drag of shuttlecock 1 more reliably.
Fig. 6～Figure 10 is the schematic diagram of variation of converged fixed portion that is used to illustrate the embodiment 1 of shuttlecock of the present invention illustrated in figures 1 and 2.Below the variation of the converged fixed portion 41 of shuttlecock 1 of the present invention is described.
The flat shape of the converged fixed portion 41 of shuttlecock shown in Figure 6 is a quadrangle.In this converged fixed portion 41, the bight is round.In addition, the converged fixed portion 41 of artificial feather 3 be configured in along the length on the direction of axle 7 be L0 feather main part 5, from zone along the central portion of axle 7 directions to base main body 2 (not shown) side.The length L 1 along axle 7 directions in the zone of configuration converged fixed portion 41 comparatively it is desirable to be more than 40% below 65% of above-mentioned length L 0, and even more ideal is is more than 40% below 50% of above-mentioned length L 0.In addition, at least a portion of converged fixed portion 41 is the zone by 7 one side of the mid point between the end that is formed on axle 7 and feather main part 5 on the width (in the peripheral part feather main part 5 of Fig. 6 and that axle 7 is relative away from the part of axle 7) at artificial feather 3 with the vertical direction of axle 7.Promptly, consider the central shaft 22 of axle 7 shown in Figure 6 and passing in the feather main part 5 on the width away from the end of axle 7 and the line segment 23 parallel with this central shaft 22.In addition, if stipulated to pass mid point between this central shaft 22 and the line segment 23, the line segment 24 parallel with central shaft 22, at least a portion that then comparatively it is desirable to converged fixed portion 41 be arranged in feather main part 5 by a line segment 24 and 7 zone that surround.
The flat shape of the converged fixed portion 41 of shuttlecock shown in Figure 7 is rectangle (or linear).Converged fixed portion 41 prolongs in the direction along axle 7.If shape as mentioned above, then can along on the direction of axle 7 on a large scale in keep the overlap condition of feather main part 5.
The flat shape of the converged fixed portion 41 of shuttlecock shown in Figure 8 is a triangle.The direction of an edge axle 7 of the periphery of converged fixed portion 41 prolongs, the relative bight, the limit with prolonging along this direction of 7 of converged fixed portion 41 is configured in the position of more leaning on base body 2 (not shown) side than the central portion on this limit in addition.By making this shape, can the accomplished such effect of dispersion that puts on the load in the converged fixed portion 41.
The converged fixed portion 41 of shuttlecock shown in Figure 9 is made of the fixed part of a plurality of point-like.The flat shape of each fixed part is circular, but also can be other arbitrary shapes.In addition, the zone that fixed part disposed can also be the rectangle or the oval-shaped zone of extending along the direction of axle 7.If as mentioned above, under the state of the area (the total area of the fixed part of point-like) of the part that reduces actual fused, can in very big zone (zone that fixed part distributed of point-like), keep the overlap condition of feather main part 5.
The converged fixed portion 41 of shuttlecock shown in Figure 10 is made of two tetragonal fixed parts.The flat shape of each fixed part is a quadrangle, but also can be other arbitrary shapes (for example, circle, ellipse, polygons etc.).In addition, also can each fixed part big or small inequality, and dispose discrepant fixed part on two or three above a plurality of sizes.By making this shape, for example in each fixed part comes off, and other fixed part also can work, and can keep the shape of shuttlecock.In addition, the quality that can not only suppress shuttlecock increases, can also feather main part 5 on a large scale in dispose converged fixed portion 41.
In addition, above-mentioned converged fixed portion 41 is shaped as illustration, and the shape of converged fixed portion 41 can be made other arbitrary shapes.In addition, the condition in the zone that disposed of the illustrated converged fixed portion 41 of Fig. 6 can also be applicable to Fig. 7～converged fixed portion 41 shown in Figure 10.
Then, the structure to the artificial feather 3 that constitutes shuttlecock illustrated in figures 1 and 21 describes.Figure 11 is that expression constitutes the floor map of the shuttlecock of shuttlecock illustrated in figures 1 and 2 with the structure of artificial feather.Figure 12 is the generalized section of the line segment XII-XII of Figure 11.Figure 13 is the generalized section of the line segment XIII-XIII of Figure 11.Figure 14 is the generalized section of the line segment XIV-XIV of Figure 11.Figure 15 is the generalized section of the line segment XV-XV of Figure 11.
With reference to Figure 11～Figure 15, the artificial feather 3 that constitutes shuttlecock 1 illustrated in figures 1 and 2 is made of with the axle 7 that is connected with this feather main part 5 feather main part 5.Axle 7 is by constituting with the affixed axial region 10 that is connected with feather main part 5 from the pinna rachis portion 8 of the outstanding forms configuration of feather main part 5 and substantial middle portion at feather main part 5.Pinna rachis portion 8 and the form configuration of affixed axial region 10 to extend along the same line constitute a continuous axle 7.
Feather main part 5 is connected with the maintained protuberance 12 of the state of the inside that is embedded in pinna rachis portion 8.Feather main part 5 and protuberance 12 constitute a flat member 9.
As shown in figure 12, axle 7 along with from root (end of the opposition side of the right-hand end of Figure 12 or the side that pinna rachis portion 8, links to each other) with affixed axial region 10 towards leading section (end of the opposition side of the left end of Figure 12 or the side that in affixed axial region 10, links to each other) with pinna rachis portion 8, spools 7 diameter diminishes gradually.In addition, as Figure 13～shown in Figure 15, the cross sectional shape on the direction (direction of quadrature) of intersecting with the extending direction of axle 7 is a quadrangle, more specifically is rhombus.In addition, the cross sectional shape of axle 7 is not limited to above-mentioned quadrangle, can adopt arbitrary shape.For example, as the cross sectional shape of axle 7, also can adopt ellipse that the length on the direction that the bearing of trend with flat member 9 intersects (Figure 13 vertically) grows than the length on the extending direction of this flat member (Figure 13 laterally) etc.
In addition, for axle 7, as shown in Figure 12 and Figure 13, in the root side of axle 7, flat member 9 is the state (state that flat member 9 is buried underground with circular-arc cross sectional shape in the inside of axle 7) that is embedded in the inside of axle 7.But as Figure 14 and shown in Figure 15, towards the leading section side of axle 7, flat member 9 becomes the state (flat member 9 becomes the state that contacts, fixes with the surface of axle 7) that exposes on the surface of axle 7 more.
In addition, the configuration of the flat member 9 of axle on 7 is not limited to Figure 11～shown in Figure 15, being embedded in the inside of axle 7 and the situation of the state that exposes on the surface of axle 7 at central portion and leading section side, the flat member 9 of axle 7 at root side, the flat member 9 of axle 7, can also be other forms.For example, also can be the root side of axle 7 and central portion, flat member 9 be embedded in axle 7 inside and at the leading section side of axle 7, the state that flat member 9 exposes on the surface of axle 7.It perhaps also can be the state that all parts, the flat member 9 of root side, central portion and leading section side at axle 7 is embedded in the inside of axle 7.
Then, Fig. 1, Fig. 2, Figure 11～shuttlecock 1 and shuttlecock shown in Figure 15 are carried out simple declaration with the manufacture method of artificial feather 3.At first, the manufacture method of the artificial feather 3 that such shuttlecock of the present invention shown in Figure 11 is used describes.
In the manufacture method of this artificial feather 3, at first implement nonwoven preparatory process (S10).The nonwoven of being prepared in this operation (S10) can adopt the flat member of arbitrary shape, but also can prepare to have the nonwoven that the approximate tetragonal flat shape of shapes shaping is justified at four angles.The thickness of this nonwoven considers that the air drag of formed artificial feather 3 and mass balance etc. suitably select.In addition, as nonwoven, can adopt the nonwoven of forming by chemical fibres such as polyester fiber, tacryls.For example, can adopt mass area ratio is 10g/m 2More than, 90g/m 2Following nonwoven.In addition, for example can adopt polyester fiber system, mass area ratio is 30g/m 2More than, 80g/m 2Below, thickness is that 0.07mm is above, the following such nonwoven of 0.13mm.In addition, comparatively it is desirable to, also can adopt mass area ratio is 40g/m 2More than, 60g/m 2Below, thickness is that 0.08mm is above, the nonwoven of the following such polyester fiber system of 0.12mm, even more ideal is that also can adopt mass area ratio is 40g/m 2More than, 50g/m 2Below, thickness is that 0.09mm is above, the nonwoven of the following such polyester fiber system of 0.11mm.
In addition, can also adopt natural fibers such as silk fabric, silk floss, cellulose fibre (paper of often saying) or the material after their coated with resins etc. replaced nonwoven.And, can also adopt resin moldings such as polyamide resin, polyester resin film, PET film (thickness is that the above 100 μ m of 50 μ m are following) to wait and replace nonwoven.And, as nonwoven, can also adopt and on the surface of above-mentioned nonwoven arbitrarily, form tectal nonwoven.As tectal formation method, for example, can adopt resin film layer is pressed on the such method of nonwoven (extrude altogether and be shaped).In addition, cover layers such as resin molding both can be to be formed on the single face of nonwoven, also can be formed on the two sides.In addition, also cover layer only can be formed at the specific part of single face or two faces.

Figure 18 is the side schematic view of the embodiment 3 of expression shuttlecock of the present invention.Figure 19 is the schematic top plan view of shuttlecock shown in Figure 180.Figure 20 is the partial cutaway schematic of structure of the part that disposes center line of expression shuttlecock shown in Figure 180.Figure 21 is the partial cutaway schematic of structure of the part that disposes interior lines of expression shuttlecock shown in Figure 180.With reference to Figure 18～Figure 21 the embodiment 3 of shuttlecock of the present invention is described.
Figure 18～shuttlecock 1 shown in Figure 21 consists essentially of the structure identical with shuttlecock shown in Figure 15 1, but be used on the fixing means that the laminated section (lap) of the feather main part 5 of artificial feather 3 is fixed different.Promptly, in order to keep the stacked state of many artificial feathers 3, employing center line 15 and interior lines 17.As described later, this center line 15 and interior lines 17 are configured to stipulate the position relation of many artificial feathers 3.Below, be specifically described with reference to the configuration of Figure 20 and Figure 21 center line 15 and interior lines 17.
As shown in figure 20, center line 15 is configured to pass feather main part 5 zones respect to one another (passing between the stacked feather main part 5) of adjacent artificial feather 3 around becoming the part of the feather main part 5 of stacked state around the axle 7 of artificial feather 3 and at adjacent artificial feather 3.Because as mentioned above in the stacked part of feather main part 5, center line 15 passes between the stacked feather main part 5, the lamination order that therefore can suppress feather main part 5 changes the generation of (for example, the impact that impacts because of racket causes that the lamination order of feather main part 5 changes) such problem in the use of shuttlecock.
In addition, as shown in figure 21, interior lines 17 are the same with center line 15 shown in Figure 20, around the axle 7 of artificial feather 3.In addition, interior lines 17 are configured to arrive from the interior all side that is arranged in many circular artificial feathers 3 axle 7 of adjacent other artificial feather 3, and successively around this 7 around.If as mentioned above, as can be known, interior lines 17 are along the interior all side configurations that are arranged in circular artificial feather 3 from Figure 19 and Figure 21.Therefore, when shuttlecock 1 uses, can suppress all sides of feather main part 5 (the interior lines 17 place sides) bending of artificial feather 3 inwardly.Consequently, can suppress the generation of the such problem of the very big change of characteristics such as air drag of shuttlecock 1.
Above-mentioned center line 15 and interior lines 17 are as Figure 18 and shown in Figure 19ly be configured to circle-shaped will be arranged in many circular artificial feather 3 whole modes fixed to one another.In addition, Figure 18～such configuration shown in Figure 21 for example can be carried out by allowing the operator make with pin etc. in these center lines 15 and interior lines 17.Be configured to circle-shaped center line 15 and interior lines 17 the square end portion that begins to make is linked with the opposing party end of finishing to make, and the part of unnecessary line sheared near knotting remove.Comparatively it is desirable to, wait by coating adhesive at this place of knotting to form protective layer.By forming such protective layer, can prevent from that this knots when shuttlecock 1 is impacted by racket to untie.
In addition, any materials such as silk floss or resin can be adopted in center line 15 and interior lines 17, but comparatively it is desirable to adopt the line of polyester.In addition, center line 15 and interior lines 17 comparatively it is desirable to adopt the line of light weight in order as possible the center of gravity of shuttlecock 1 etc. not to be brought influence as far as possible.For example, as the line that is adopted, also can adopt the line of No. 50 polyester.At this moment, the quality of the line that uses as center line 15 is about 0.02g.If the quality of this degree though can bring a little influence to the position of centre of gravity of shuttlecock 1, is thought to almost not influence of flying quality.
In addition, the configuration of center line 15 and interior lines 17 both can be disposed on the different position of the distance of base body 2 with shown in Figure 19 as Figure 18, also can be in position configuration these center lines 15 and the interior lines 17 identical apart from essence of distance base body 2.But, when the lamination order of fixing artificial feather 3 and also utilize center line 15 and the situation of interior lines 17 as strength member under, comparatively it is desirable to, center line 15 is different apart from the distance of base body 2 with interior lines 17.In addition, if consider to prevent feather main part 5 bending (curling) to the inside of artificial feather 3, then more effective is that interior lines 17 are configured in than the position of center line 15 further from base body 2.
The manufacture method of the shuttlecock 1 of Figure 18～shown in Figure 21 manufacture method with shuttlecock illustrated in figures 1 and 2 basically is identical, but the operation of implementing configuration center line 15 and interior lines 17 replaces forming in the above-mentioned assembling procedure (S200) converged fixed portion 41.Center line 15 and interior lines 17 for example also can be configured by operator's the operation of making.In addition, as interior lines 17 and center line 15 etc., can adopt any materials, but for example also can adopt resins such as silk floss or polyester as mentioned above as material.Like this, just, can make Figure 18 and shuttlecock 1 shown in Figure 19.

Figure 27 is the schematic top plan view of the embodiment 5 of expression shuttlecock of the present invention.Figure 28 is that expression constitutes the floor map of the shuttlecock of shuttlecock shown in Figure 27 with the structure of artificial feather.With reference to Figure 27 and Figure 28 the embodiment 5 of shuttlecock of the present invention is described.
With reference to Figure 27 and Figure 28, shuttlecock 1 consists essentially of the structure identical with shuttlecock illustrated in figures 1 and 2, but different with shuttlecock illustrated in figures 1 and 2 in the configuration of the shape of artificial feather 3 and adjacent artificial feather 3 converged fixed portion 41 each other.Promptly, as shown in figure 28, the artificial feather 3 that constitutes the shuttlecock 1 of present embodiment consists essentially of the structure identical with artificial feather shown in Figure 11 3, but different in shape at feather main part 5.Particularly, as shown in figure 28, in the artificial feather 3 that constitutes shuttlecock 1 shown in Figure 27, on feather main part 5, be formed with towards the side-prominent extension 50 of periphery.Extension 50 is towards away from the direction of axle 7 (particularly be the direction of intersecting with axle 7, more specifically be direction with axle 7 quadratures) prolongation.In shuttlecock shown in Figure 27 1, this extension 50 of artificial feather 3 extends to the position of the axle 7 of crossing this other artificial feather 3 on interior all sides of other adjacent artificial feathers 3.In addition, crossing on this position of 7, extension 50 is connected and fixed by converged fixed portion 41 with the feather main part 5 of other artificial feathers 3.In addition, in converged fixed portion 41, also can stiffener 43 be disposed between the feather main part 5 of extension 50 and other artificial feather 3 as shown in Figure 3.In addition, the flat shape of converged fixed portion 41 for example also can be the arbitrary shape as Fig. 8～shown in Figure 10.
In addition, about the configuration of converged fixed portion 41, what at least a portion was formed on artificial feather 3 is the zone by 7 one side of the mid point between the end (on the feather main part of Figure 27 in the peripheral part relative with axle 7 away from the part of axle 7) of axle 7 and feather main part 5 (with reference to Figure 28) on the width with the vertical direction of axle 7 (with reference to Figure 28).Promptly, the central shaft 22 of considering axle 7 shown in Figure 27 with on the feather main part, pass on the width end away from axle 7, the line segment 23 parallel with this central shaft 22.In addition, if define the mid point that passes between this central shaft 22 and the line segment 23, the line segment 24 parallel with central shaft 22, at least a portion that then comparatively it is desirable to converged fixed portion 41 be positioned at feather main part 5 by a line segment 24 and 7 zone that surround.In addition, the peripheral part relative with axle 7 is meant the meaning of peripheral part in the zone that does not comprise extension 50 of feather main part 5 in the above-mentioned feather main part.
Even form this structure, also can similarly keep the stacked state of the feather main part 5 of artificial feather 3 with shuttlecock 1 shown in Figure 1.And, because converged fixed portion 41 is disposed on the position of the axle 7 of crossing other adjacent artificial feathers 3, therefore compare with the situation of the front side of the axle 7 of the artificial feather 3 that as shown in Figure 1 converged fixed portion 41 is disposed at other, the free degree of the free degree of the shape of artificial feather 3 and the configuration of converged fixed portion 41 becomes big.Therefore, if form structure shown in Figure 27, in the size that all torsion angle of artificial feather 3 can be maintained regulation from the central authorities of feather main part 5 to front (away from the end side on the direction of base body 2).In addition, because converged fixed portion 41 is formed at from the outstanding extension 50 of the periphery of feather main part 5, therefore for adjacent artificial feather 3, the feather main part 5 that can observe from the extending direction of axle 7 angulation (torsion angle) is each other set fully greatly.That is to say, can realize the close shape of shape with the natural feather ball.
In addition, the shape of extension 50 is not limited to shape as shown in figure 28, can also be other arbitrary shapes.For example, in order to set the size of converged fixed portion 41 fully big, can also make the width of the leading section (away from the end on axle 7 directions) of extension 50 set greatlyyer than the width of other parts of extension 50.In addition, on feather main part 5, observe from axle 7, the part of side's side is than the structure of the part of the opposing party side big (width of the part of the side's side on the direction of intersecting with axle 7 is bigger than the width of the part of the opposing party side) as a whole, and the part of spools 7 position that extending in the part of side's side can also be crossed other adjacent artificial feathers 3 is as extension 50.In addition, also converged fixed portion 41 similarly can be disposed on the position of not crossing axle 7 with shuttlecock 1 shown in Figure 1.
Figure 29 is the schematic top plan view of variation of the embodiment 5 of expression shuttlecock of the present invention shown in Figure 27.With reference to Figure 29 the variation of the embodiment 5 of shuttlecock 1 of the present invention is described.
Shuttlecock 1 shown in Figure 29 consists essentially of the structure identical with shuttlecock shown in Figure 27 1, but be provided with on the point of interior lines 17 different.The configuration identical with the interior lines 17 that are arranged at Fig. 4 and shuttlecock 1 shown in Figure 5 can be carried out in interior lines 17.If as mentioned above, then except the effect of shuttlecock shown in Figure 27 1, can also suppress all sides of feather main part (the interior lines 17 place sides) bending of artificial feather 3 inwardly.Consequently, can suppress the generation of the such problem of the very big change of characteristics such as air drag of shuttlecock 1 more reliably.In addition, Figure 29 has represented interior lines 17 are applied to the example of shuttlecock shown in Figure 27 1, but center line 15 shown in also Figure 18 can being waited or outside line 19 shown in Figure 22 etc. are arranged on the shuttlecock shown in Figure 27 1.In addition, also these center lines 15, interior lines 17, outside line 19 can be made up arbitrarily and be applied on the shuttlecock shown in Figure 27 1.
In addition, in Figure 27 and shuttlecock 1 shown in Figure 29, form converged fixed portion 41 as the fixed part of extension 50, but the portion that is adhesively fixed 31 that can also form employing adhesive member 33 as shown in figure 17 is as this fixed part with the feather main part 5 of other artificial feathers 3.
Though the part that repeats with an above-mentioned embodiment part is also arranged, characteristic structure of the present invention is listed below.
Shuttlecock for badminton 1 of the present invention comprises hemispheric base body 2 and the artificial feather 3 of Duo Gen.Many artificial feathers 3 comprise feather portion and the axle 7 that is connected with this feather portion.In addition, many artificial feathers 3 are to be configured to ring-type and partly overlapping form is fixed in base body 2.At least a portion fusion after coagulation of the part that overlaps each other of the feather portion by making artificial feather 3, thus converged fixed portion 41 formed as the fusion portion that the lap of feather portion is fixed.
If as mentioned above, even then constitute under the situation of the low artificial feather 3 of the feather (natural feather) of aquatic bird of natural feather ball in the rigidity that adopts axle 7 and strength ratio, the converged fixed portion 41 of playing fusion portion effect by formation, thus stacked state that can this artificial feather 3 and shape maintains are in initial situation.Therefore, can suppress because of the stacked state change of artificial feather 3 or the flying quality variation of artificial feather 3 distortion causing shuttlecock 1.
In addition, owing to converged fixed portion 41 is fixed to one another with adjacent artificial feather 3 for the stacked state of keeping many artificial feathers 3, therefore also can play the effect of strength member.Therefore, the intensity of shuttlecock 1 can be improved, and the durability of shuttlecock 1 can be improved on the result.
In addition, by make artificial feather 3 stacked part at least a portion fusion, solidify again, thereby can not carry out forming converged fixed portion 41 under the situation of configured in advance such as bonding agent etc.Therefore, can simplify the manufacturing process of shuttlecock 1.
In above-mentioned shuttlecock for badminton 1, as Fig. 6 and shown in Figure 27, it is the zone by 7 one side of the mid point between the end of axle 7 and feather portion on the width that at least a portion of converged fixed portion 41 also can be formed on the axle 7 vertical directions of feather portion.Particularly, shown in Fig. 6 waits, under the situation that is not formed with extension 50 as shown in figure 26 on the feather main part 5, comparatively it is desirable to, at least a portion of converged fixed portion 41 be formed on feather main part 5 by a line segment shown in Figure 6 24 and axle 7 zones that surround.In addition, as shown in figure 27, be formed with at feather main part 5 under the situation of extension 50, comparatively it is desirable to, at least a portion that is formed at the converged fixed portion 41 of extension 50 be positioned at feather main part 5 by a line segment shown in Figure 27 24 and axle 7 zones that surround.In addition, even more ideal is, converged fixed portion 41 be formed at by this 7 and the inside in the zone that surrounds of line segment 24.At this moment, artificial feather 3 has sufficient width in the part of the feather portion in converged fixed portion 41 outsides, and can keep the torsion angle of artificial feather 3.
In above-mentioned shuttlecock for badminton 1, converged fixed portion 41 is between the feather main part 5 on the part that overlaps each other of adjacent feather main part 5 and also can comprise the stiffener 43 affixed with feather main part 5.At this moment, though artificial feather 3 the thin thickness of stacked part, also can fully improve the intensity of converged fixed portion 41 by configuration stiffener 43.
In above-mentioned shuttlecock for badminton 1, stiffener 43 also can come with above-mentioned feather main part 5 affixed by the fusion after coagulation.
