In other words, center line 15 is arranged to extend around the axle 7 of each artificial feather 3, and extends also through adjacent Region between the feather part 5 of artificial feather 3, adjacent artificial's feather 3 is weighed each other in the feather part 5 of adjacent artificial's feather 3 In folded region (passing through that is, so that between the feather part 5 overlapped each other) relative to each other.Center line 15 feather part 5 this Passed through in the region that sample overlaps each other between overlapping feather part 5.Thus, become to suppress in the mistake using shuttlecock The overlapped sequential of journey mesoptile part 5 changes (for example, the overlapped sequential of feather part 5 changes due to the influence that racket is hit) The problem of generation.

As shown in figs. 1 and 4, above-mentioned center line 15 is placed circumferentially, makes many artificial feathers 3 of all arrangements circlewise It is fixed to one another.In addition, center line 15 can be set as shown in figs. 1 and 4, for example, sewed and fastened by workman's pin or the like. Thus, the generation for the problem of being changed by the overlapped sequential suppressed in feather part 5 during using shuttlecock 1, can be obtained There must be the shuttlecock 1 of fabulous durability.

In addition, setting center line 15 circumferentially that there is one end in the section start of sewing and have in the destination county of sewing The other end.The one end and the other end are tied mutually, and cut the remaining part of line near knot and remove.It is preferred that Ground is that the knot is equipped with adhesive or the like to form protective layer in its surface.By forming this protective layer, It can prevent knot from unclamping when shuttlecock 1 is with ball-bat impact.

Although in addition, any material of such as cotton thread or resin can be used to make center line 15, it is preferred that using by washing American run into line.In addition, center line 15 is made preferably by most light possibility material, to prevent shuttlecock 1 as much as possible Center of gravity etc be affected.For example, can be using No. 30 polyester threads.In this case, the quality of the line as center line 15 is big It is approximately 0.02g.It is believed that the quality of this level on flight characteristics substantially without influence, although the position of centre of gravity of shuttlecock 1 can It is affected to a certain extent.In addition, when placing center line 15, the distance of itself and matrix 2 can be optionally set.

With reference to Fig. 2, forming the artificial feather 3 of the shuttlecock 1 shown in Fig. 1 includes feather part 5 and is connected to feather part 5 Axle 7.Axle 7 is formed by feather shaft portion 8 and fixed shaft portion 10, and feather shaft portion 8 is arranged to protrude from feather part 5, Gu Dead axle part 10 is about connected to feather part 5 in the center section of feather part 5.Feather shaft portion 8 and fixed shaft portion 10 It is set along the extension of identical line to form a continuous axle 7.

Axle 7 can be made for example with nylon, and preferably using nylon 12, nylon 11, nylon 10, NYLON610, Buddhist nun Dragon 612 and nylon 1010.In order to increase the intensity of axle 7, potassium titanate crystal whisker, glass fibre or the like can be also added to Buddhist nun Dragon.In addition, also axle 7 can be made using makrolon, polypropylene and polyethylene.

(shape of cross section is along the direction perpendicular to the bearing of trend of axle 7 to the shape of cross section of the axle 7 of artificial feather 3 Intercepted) can be any shape, but rectangle is may, for example, be, as illustrated in Figures 5 and 6.

Reference picture 2, feather part 5 includes froth bed and axle fixed bed, and they are configured to fixed shaft portion 10 to be clipped in Between them, and also include being used to make the adhesion layer that froth bed and axle fixed bed are fixed to one another.In other words, in feather part 5 In, froth bed and axle fixed bed are stacked into fixed shaft portion 10 makes axle 7 press from both sides between them.Then, feather part 5 exists The side of the shorter side of axle 7 shown in Fig. 5 is upwardly extended.In addition, adhesion layer is arranged in feather part 5, so that bubble Foam layer and axle fixed bed interconnect and also make to fix shaft portion 10 be fixedly attached to it is each in froth bed and axle fixed bed It is individual.In addition, from another perspective, in feather part 5, the bubble in outer circumferential sides in the structure positioned at shuttlecock 1 One layer of adhesion layer is stacked in foam layer.On the adhesion layer, fixed shaft portion is arranged to be positioned in the big of adhesion layer and froth bed Cause in core.Then, another adhesion layer is configured to extend to one layer of adhesion layer from the top of the fixation shaft portion 10 On.Then, axle fixed bed is arranged on other adhesion layer.

In artificial feather 3, axle 7 can be bent towards froth bed side (that is, towards the outer circumferential sides in shuttlecock 1).From From the point of view of another angle, axle 7 bends to towards axle fixed bed side and protruded.In addition, feather part 5 can be in the extension across axle 7 On the direction (for example, bearing of trend perpendicular to axle 7 and width of the extension of the surface along feather part 5) in direction towards Froth bed (outer circumferential sides towards in shuttlecock 1) (that is, the so bending of feather part 5 towards axle fixed bed side so as to protrude) Bending.In this case, artificial feather 3 axle 7 bearing of trend bend state and feather part 5 it is above-mentioned across The state of the direction bending of the bearing of trend of axle 7 can occur simultaneously, or can only occur one in these bendings.It can lead to Commonly known method is crossed to implement this case of bending, such as it is a kind of that hot place is carried out to axle 7 and the composition material of feather part 5 The method of reason or a kind of method that axle 7 and the component material of feather part 5 are just formed with case of bending from beginning.

In this case, resin foam is can be for example for forming the material of froth bed, and is, for example, specifically poly- Vinyl foam (a kind of foam being made up of polyethylene).In addition, axle fixed bed similarly can be made of resin foam.In addition, Except polyethylene, axle fixed bed can also be using any film being such as made up of resin or the like or adhesive-bonded fabric Material is made.

In addition, adhesion layer can be made of such as two-sided tape.In artificial feather 3, polyethylene can be used for bubble Foam layer and axle fixed bed.In which case it is preferred to which ground is the polyethylene in the bearing of trend perpendicular to Fig. 2 axis 7 Direction (horizontal direction in Fig. 2) is squeezed.In this case, axle 7 is fixedly attached to feather part 5, so as to cross to be formed The direction of extrusion of the polyethylene of feather part 5.Therefore, the defect hair that feather part 5 is broken in the bearing of trend of axle 7 is made Raw possibility reduction is possibly realized.

The matrix 2 for forming shuttlecock 1 is constructed so as to, i.e. matrix lower floor 2a and matrix interlayer 2b as shown in Figure 3 is stacked Together, the excircle film 2d that they have is covered, and reinforcer 2c stack into covering matrix interlayer 2b and Overlay film 2d.For example, matrix lower floor 2a can be formed by the natural material of such as cork.Matrix lower floor 2a has hemispherical shape, It is also apparent in Fig. 3.Matrix interlayer 2b, which is set, to be deposited on matrix lower floor 2a (so as to be connected to matrix lower floor 2a flat surface element).Matrix interlayer 2b has such as cylindrical shape.Although matrix interlayer can be by any material system Into, it is preferred to use flexible material.In addition, matrix interlayer 2b can be for example using the artificial material of similar resin material (synthetic cork) is formed, and more preferably uses foamed resin.However, natural cork can be used to carry out generation for matrix interlayer 2b Formed for synthetic cork.According to above, the end section of matrix 2 is formed by these matrix lower floor 2a and matrix interlayer 2b.

Reinforcer 2c is configured to be deposited in the end section.Reinforcer 2c is formed as such as disc.Reinforcer 2c It can be formed using any material of such as resin.Reinforcer 2c is high than the hardness for the material for for example forming matrix interlayer 2b. In addition, hardness of the matrix lower floor 2a also than the material for forming matrix interlayer 2b is high.Reinforcer 2c is than matrix lower floor 2a's Hardness is high.Matrix lower floor 2a, matrix interlayer 2b and reinforcer 2c are fixedly secured to one another using adhesive or the like.With Afterwards, overlay film 2d so sets to cover matrix lower floor 2a and matrix interlayer 2b excircle.Overlay film 2d can use any material Material is formed, and is formed for example with synthetic leather.

As shown in figure 5, reinforcer 2c is provided with the multiple fixing holes 63 for being aligned to annular, whereby 7 points of the axle of artificial feather 3 It is not inserted into and fixes along the excircle of these fixing holes.Each axle 7 of artificial feather 3 is inserted to by these fixing holes Corresponding one passes through reinforcer 2c and reaches matrix interlayer 2b inside in 63, and each axle 7 is fixed on wherein.

Axle 7 (feather shaft portion 8) has width, and the width is included in its end section (in the phase with fixed shaft portion 10 To on side) width t₁With the width t in its body portion (on the side close to fixed shaft portion 10)₂.Width t₁And width Spend t₂Difference, and width t₁Less than width t₂.In other words, axle 7 (feather shaft portion 8) is formed with tapered form.At this In kind of situation, the initial diameter of fixing hole 63 (axle 7 be inserted into before diameter) is set to be greater than the width t of axle 7₁And be less than The width t of axle 7₂。

Because the initial diameter of fixing hole 63 is more than the width t of axle 7₁, axle 7 can be inserted easily fixing hole 63.In addition, The initial diameter of fixing hole 63 is less than the width t of axle 7₂.Therefore, it is fixed by the way that the axle 7 of artificial feather 3 is inserted into fixing hole 63 Outer circumferential shape part crust deformation of the inner peripheral surface (side wall) in hole 63 along axle 7, as illustrated in Figures 5 and 6 (that is, fixing hole 63 Inner peripheral surface is extruded and deformed by the outer circumference surface of axle 7).Therefore, the first area 63a on the inner peripheral surface of fixing hole 63 and Second area 63b is deformed respectively along the first area 7a on the surface of axle 7 and second area 7b.Then, first of axle 7 is made The first area 63a of point 7a and fixing hole 63 starts that intimate contact with one another (the Part I 7a of axle 7 is squeezed against to the firstth area Domain 63a) so that axle 7 is fixedly attached to reinforcer 2c.And the Part II 7b of axle 7 is started and fixing hole 63 Second area 63b is in close contact, so that axle 7 is fixedly attached to reinforcer 2c.

It is also preferred that, there is difference in the hardness of the material for forming reinforcer 2c and the material for forming axle 7, and excellent Selection of land is the such material of selection, wherein the hardness for forming reinforcer 2c material is less than the material for forming axle 7.However, according to Use condition, can so select material, wherein the hardness for forming reinforcer 2c material is higher than the material for forming axle 7.Make herein Hardness is JIS K7215, for example durometer hardness D.

As it can be seen in figures 5 and 6, the shape of cross section in order to show fixing hole 63 and axle 7 in intelligible mode, fixing hole 63 First area 63a (see Fig. 6) and axle 7 Part I 7a it is intimate contact with one another.Also, the second area 63b of fixing hole 63 Also the Part II 7b with axle 7 is in close contact.

Then, the end section of the axle 7 of insertion reinforcer 2c fixing hole 63 is placed sinking and arrives matrix interlayer 2b.This It result in the state that axle 7 is fixedly attached to the matrix interlayer 2b and reinforcer 2c of matrix 2.It is also preferred that in matrix Interbed 2b is previously provided with small patchhole, and the patchhole (touches reinforcer 2c's from matrix interlayer 2b highest face temperature Surface) matrix interlayer 2b is extended to connect with fixing hole 63.Therefore, the axle 7 of reinforcer 2c fixing hole 63 is inserted End section is inserted into the patchhole in matrix interlayer 2b, so that axle 7 is inserted easily into reach matrix interlayer 2b inside (compared with being not provided with the situation of patchhole in wherein in the base interbed 2b).

The axle 7 of the artificial feather 3 being made up of artificial resin material generally with the material of such as cork contacted It is inferior in terms of bonding.Therefore, in order to increase viscosity, reinforcer 2c is placed on the matrix interlayer 2b that axle 7 is inserted. Because, the initial diameter of the fixing hole 63 in reinforcer 2c is less than the width t of axle 7₂, and the insertion of axle 7 causes fixation The inner circumferential side surface in hole 63 is partly extruded and deformed along the outer circumferential shape of axle 7, so as to be inserted into reinforcer 2c The axle 7 of fixing hole 63 be fixedly secured to reinforcer 2c.

By the patchhole being pressed into axle 7 in matrix interlayer 2b, the inner peripheral surface of fixing hole 63 expands, and close The surface of axle 7 is fixed firmly to, so that axle 7 is fixedly secured to matrix interlayer 2b.In order to further increase in matrix Viscosity between interbed 2b and axle 7, preferably matrix interlayer 2b is formed by elastomeric material, and it is also preferred that matrix Patchhole in the 2b of intermediate layer has small enough to make axle 7 to be inserted into diameter therein.

As described above, by the patchhole in the fixing hole 63 and matrix interlayer 2b in reinforcer 2c, axle 7 can be consolidated Surely matrix 2 is arrived to be in close contact with the matrix 2 in the case where being required for adhesive.Thus there is provided a kind of with high The shuttlecock of durability, and it can obtain with the manufacture labour of reduction and the excessively simple manufacturing process of cost.In addition, The deformation of whole whole feathers can be suppressed by increasing the viscosity between matrix interlayer 2b and axle 7, had so as to provide The shuttlecock of the flight characteristics of high stability.

For example, as shown in Figures 3 and 4, multiple axles 7 extend respectively along the direction for favouring the highest face temperature of matrix 2, and this A little axles 7 extend in a different direction.Also, every artificial feather 3 by align member (rope form fixing component 4) it is fixed so as to Formed a branch of.Even if thus, for example, power is applied into the axle 7, power along an axle 7 from the matrix interlayer 2b directions pulled out It will not apply by other axles 7 from the matrix interlayer 2b directions pulled out on those axles 7, because being formed together with an axle 7 These a branch of other axles 7 are upwardly extended in the side different from the bearing of trend of axle 7.Therefore, in the present embodiment, axle 7 Matrix 2 can be tightly secured to provide high durability in the case where being required for adhesive.

In addition, natural cork is easier to for example be made a mess of due to axle 7 is inserted into the cork, but synthetic cork's plug is not Easily make a mess of very much.Therefore it is more preferable to which ground is, using artificial material as the material for forming matrix interlayer 2b, but naturally Material may also used as being formed matrix interlayer 2b material.The method of the manufacture shuttlecock 1 shown in Fig. 1 to 6 is described below.
