Artificial feather for shuttlecock and shuttlecock

Technical field

The present invention relates to the artificial feather for the shuttlecock of badminton.Particularly, the present invention relates to a kind of improvement technology, be mainly used in alleviating the accessory pinna weight partly of artificial feather, improve its durability.In addition, the present invention relates to use the shuttlecock of artificial feather.

Background technology

As the shuttlecock of badminton, its feather is aquatic bird feather (shuttlecock of natural feather) and artificial feather (shuttlecock of artificial feather), and described artificial feather is made with nylon resin etc. is artificial.

As everyone knows, the shuttlecock of natural feather has such structure: utilize goose, and approximately 16 natural feathers of duck etc., and the end of described feather trunk embedding hemispherical ball holder (bottom), described ball holder is made by covering cork rindy.And the feather that is used for the shuttlecock of natural feather has the feature of little and extremely light proportion.For example, the proportion of trunk portion is approximately 0.4 and accessory pinna partly is approximately 0.15.In addition, natural feather has strong rigidity, and therefore can experience unique flying quality and comfortable sensation when impacting the shuttlecock of natural feather.

But, feather as the material of the shuttlecock of natural feather is collected from above-mentioned natural aquatic bird, in addition, the feather of the specific part of aquatic bird is applicable to shuttlecock, this does not also mean that the feather that can use from any part of aquatic bird, and the quantity of the feather that is used for shuttlecock that therefore can collect from an aquatic bird is very little quantity.In other words, the feather quantity of the shuttlecock that is used for natural feather of manufacturing is limited.In addition, the goose that is used as food was once the main source of feather, and in recent years due to bird flu, a large amount of geese is processed.Therefore, the acquisition of material is estimated to become more difficult, and the price of the shuttlecock of natural feather will further rise in the future.

Simultaneously, shuttlecock as artificial feather, the shuttlecock of the resin feather that forms with circular integration is well-known, but, the self-movement unlike the feather of the shuttlecock of natural feather of the feather of the shuttlecock of these artificial feathers, thus be difficult to reach the flying quality of the shuttlecock of similar natural feather.Due to these reasons, proposed to imitate the shuttlecock of the artificial feather of feather, described in following PTL 1 and 2.At this, when making based on ornithology knowledge when setting up corresponding relation between natural feather each several part and artificial feather each several part, part corresponding to natural feather accessory pinna and pinna rachis will be called accessory pinna part and pinna rachis part, thereby will be called the pen feather part and stretch out from accessory pinna corresponding to those as a part of pinna rachis, part that be called basis and pen feather, obscure with feather avoiding.Under these prerequisites, the artificial feather of describing in PTL1 has the accessory pinna part of double-layer structure, comprises foam layers and trunk fixed bed, both uses same plane to adhere to each other, and have the pinna rachis part that is fixed on interlayer, thereby the pen feather part is partly stretched out from accessory pinna.

Further, the artificial feather of describing in PTL2 has such structure, and wherein an end of accessory pinna part is formed with extension, and described extension is made by non-weaving cloth, it stretches out on the bearing of trend of pinna rachis part, and has the extension that is embedded in the pinna rachis part.

Summary of the invention

Technical problem

The artificial feather that is used for shuttlecock need possess various performances, for example is similar to impacting of natural feather and feels and flying quality.Especially, accessory pinna has partly consisted of the almost Zone Full of monolithic artificial feather, therefore, the characteristic that makes accessory pinna characteristic partly greatly imitate natural feather, this is most important.

Particularly, be used for the set of the relatively hard feather (barb) that the accessory pinna of natural feather of the shuttlecock of natural feather grows from pinna rachis for each.Due to this structure, natural feather has the moderate characteristics of hardness (shape conservation degree), although thin and light, even if also be difficult for deformation during high-speed flight aloft.

Therefore, need to be from comprising that under the different situations such as material, structure and similar aspect, each angle is studied, so that the accessory pinna of artificial feather partly has aforementioned feature.But it is very difficult satisfying all these conditions.For example, the artificial feather described in aforementioned PTL1 uses foamed polyethylene as its foams, and this foam layers to be considered to be the accessory pinna part substantially, be coated with the trunk fixed bed on whole of accessory pinna part.Inevitably, foams are made thickly, and this is that hardness will reduce because when accessory pinna during partly with thin film fabrication, with weight reduction.Like this, if the Zone Full of accessory pinna part is all supported by foams, loss of weight will become difficult.In addition, the foamed polyethylene poor adhesion, so make foam layers and trunk fixed bed stick to the wide region that forms the accessory pinna part, described zone has double-faced adhesive tape, so that foam layers and trunk fixed bed are fixed as the laminar state.Therefore, contrast natural feather ball, it is difficult that loss of weight will become.Problem is, if the weight saving of accessory pinna part, the proportion of shuttlecock will descend, and turn performance reduces, and causes disequilibrium.

The accessory pinna of the artificial feather described in PTL 2 partly uses non-weaving cloth, therefore is contemplated to alleviating of accessory pinna part weight.Yet non-weaving cloth lacks rigidity, and therefore, it is difficult to recover original shape when impacting with sudden force.In addition, non-weaving cloth poor durability.Especially, a kind of possibility being arranged is that fiber can disintegrate and scatter when impacting.Disintegrate as fruit fiber, accessory pinna partly will easily break.In fact, as product, the deteriorated of its outward appearance is also a problem.

The specific embodiment

The structure of the shuttlecock of artificial feather

Fig. 1 and Fig. 2 have showed that the shuttlecock 1(of artificial feather is hereinafter referred to as shuttlecock) external view, it comprises artificial feather 10, this artificial feather 10 has the basic structure total with the embodiment of the present invention.Fig. 1 is the perspective view of the shuttlecock 1 watched from downside, and wherein bottom 2 is in downside, the perspective view of Fig. 2 for seeing from the top.Imitate a plurality of (for example 16) artificial feather 10 of natural feather along the peripheral annular embedding on the smooth upper plane of spherical bottom 2, make its diameter increase near top the time, be fixed together with wire-like members (for example, cotton thread) 3 simultaneously, to form skirt shape part 4.

The embedded mode of the artificial feather 10 that described annular arranges makes the part of adjacent artificial feather 10 overlapping with the rule style.In illustrative example, in artificial feather 10, when its face towards aforementioned skirt part 4 is made as the front side, and its face towards the inboard is made as rear side, and when watching from the bottom 2 that is positioned at downside during a slice artificial feather 10, relevant artificial badminton ball 10 has the front left hand edge that the back with the artificial feather 10 adjacent in the left side stresses to fold.In fact, the anterior-posterior relation of adjacent artificial feather 10 is not limited to shown in example; The right hand edge of front can stress to fold with the back of the artificial feather 10 adjacent on the right side.

The feature of embodiments of the invention

When the shuttlecock of artificial feather is used for badminton only in order to lie fallow, the artificial feather that consists of shuttlecock realizes that lightweight, productivity ratio to a certain degree and persistence are just enough.In other words, if it is cheap and durable just enough.But, be used for those of training athlete, with have when it when replacing the final purpose of the formal shuttlecock that uses in match, the almost whole zone of accessory pinna part pattern of wants artificial feather, particularly, will greatly imitate the characteristic of natural feather, for example shape retention and impact resistance, simultaneously light as much as possible.

For example, the method that impacts that is called as " hairpin shot " in badminton is that the shuttlecock of natural feather is exclusive.This impacts method can make shuttlecock fly along unique camber line by " toe lift " and batting, makes the shuttlecock picture be applied in simultaneously powerful revolving force floating.Regenerating above-mentioned arching trajectory with the shuttlecock of artificial feather needs artificial feather to have and the closely similar feature of natural feather.Nature considers that the cost of natural feather increases, and this artificial feather must be easy to make.

To greatly affect this idea of performance of the shuttlecock of artificial feather based on the structure and material of the accessory pinna part of the bulk zone that consists of artificial feather, the inventor sums up: the most important condition that accessory pinna partly needs is except lightweight, also have suitable rigidity (shape hold facility) and good durability, be out of shape easily when flying at a high speed avoiding aloft.And, at first, thin accessory pinna has partly been used some reinforcements, with improvement shape retention energy and durability, and do not hinder the partly loss of weight of self of accessory pinna.

About the reinforcement of accessory pinna part, can consider to cover the accessory pinna part with for example film and analog.Yet, because the senior proportion of film (approximately 1.1) is large, for example, when normal film adheres to accessory pinna one side, suppose that normal film has the thickness of 20 μ m, weight has increased approximately 0.01 gram.The material of accessory pinna part has determined can not use such as adhesion methods such as heat seals, therefore will increase for film is affixed to accessory pinna must not the weight of adhesive.Therefore, make not only lightweight but also high degree of rigidity is arranged of accessory pinna part, this is difficult.

Therefore, in the embodiment corresponding to above-mentioned main summary of the invention, by forming the film of being made by the resin that accessory pinna is partly used, can realize shape retention and the durability of accessory pinna part, and not hinder the loss of weight of accessory pinna part itself.Except aforementioned main summary of the invention, in corresponding to embodiments of the invention, at first, for accessory pinna part and resin molding (strengthening membrane) have been formulated preferred material, and accessory pinna part is made by non-weaving cloth, strengthen coating for lower any: aqueous polyurethane, waterborne polyester, water polyolefin, nylon are emulsion and acrylic emulsion.In addition, effect to the Unit Weight of the reinforcement coating in the per unit zone of one of them accessory pinna part more than or equal to 1.8g/m ², be less than or equal to 27g/m ²

The present invention also is applicable to such embodiment: wherein increased the setting that is used for strengthening the accessory pinna part, and the setting that is used for realizing good flying quality, but significantly do not gain in weight, this is because loss of weight, shape retention and the durability of accessory pinna part itself are all guaranteed according to main inventive embodiment.And described embodiment has following characteristics.

Described accessory pinna partly has the reinforcement material of being made by the foam layers that is located thereon, and described pinna rachis part is clipped in the middle with the described reinforcement material that is positioned at office, described accessory pinna support portion by described accessory pinna part, and described reinforcement material is complied with the flat shape in the zone that is formed with the accessory pinna part, and described reinforcement material has a kind of like this flat shape, in this flat shape, the edge that is arranged in the office, overlapping portion of an accessory pinna part accessory pinna part adjacent with another of described shuttlecock is cut off.

Perhaps, aforementioned reinforcement material has the frame that cuts away, simultaneously towards being formed on the part of described frame with the shape rib that another adjacent artificial feather extends.In addition, the position of aforementioned rib is adjacent with aforementioned another adjacent artificial feather, and extends obliquely from the part of aforementioned frame.

Should be noted that having shuttlecock any aforementioned feature, the use artificial feather is also embodiments of the invention.Square stance, when " intersection ", be the anterior-posterior relation of adjacent accessory pinna part become anti-situation when occuring, artificial feather for the accessory pinna part with plane layout, will square stance next time with the anterior-posterior relation become again to initial relation be difficult, therefore, caused the unsettled problem of flight path.That is, because the accessory pinna of natural feather is not film shape, but the set of the feather body that grows from pinna rachis, be called barb, like this, when intersecting generation, the barb that the barb of accessory pinna passes adjacent accessory pinna slides, so crossing condition can easily become its original state again at lasting square stance.

Due to this situation, one embodiment of the present of invention have contained the shuttlecock that comprises for the means that suppress to intersect.And this shuttlecock comprises following arbitrary characteristics.

Note, can adopt for example following for the manufacture of the manufacture method according to the artificial feather 10a of the first embodiment.After becoming accessory pinna part 12, pinna rachis part 20 or reinforcement material 15 by double color mold-making or the lasting injection molding of inserted mode system, accessory pinna part 12 and reinforcement material 15 are fixed together by further double color mold-making or inserted mode system, to form moulded product, this product has accessory pinna part 12 and laminar reinforcement material 15, accompanies pinna rachis part 20 at interlayer simultaneously.After accessory pinna part 12 and pinna rachis part 20 injection moldings were integral the formula moulded product, reinforcement material can adhere to accessory pinna part 12 and stratification by utilizing adhesive or double-stick tape.Described reinforcement coating can be formed at the front of accessory pinna part 12 before injection molding, or in the process that is molded into artificial feather 10a outside or afterwards.No matter when, artificial feather 10a should be formed with the reinforcement coating that is positioned on accessory pinna part 12 at least, have the pinna rachis part 20 of the interlayer that is clipped in accessory pinna part 12 and reinforcement material 15, also have a kind of external shape, wherein pinna rachis part 20 is not exposed in accessory pinna support section 23 outwardly.

It should be noted that, herein in described the first embodiment, the base material of accessory pinna part 12 is used the thin non-weaving cloth of lightweight, and can be only just reappear the utmost point like the flat shape of the accessory pinna of natural feather by cutting, described accessory pinna part 12 has the reinforcement coating of being made by soluble polyurethane that is formed on non-woven fabric.Therefore, 12 expections of accessory pinna part have improved high rigidity effect.In addition, also solved the exclusive problem that its fiber disintegrates when impacting of non-weaving cloth.In the first embodiment, the accessory pinna part 12 of constructing by layer, and by the reinforcement material 15 that foams are made, prevented that the impulsive force when accessory pinna part 12 is impacted with sudden force by being absorbed in accessory pinna part 12 from disintegrating, not serious upset loss of weight simultaneously.

Yet the characteristics of the artificial feather 10a of the first embodiment are, it is not the layer structure of this accessory pinna part 12, and the reinforcement material 15 of foams, but the layer shape that is consisted of by accessory pinna part 12 and reinforcement material 15.Particularly, reinforcement material 15 be not even stratum cover, with consistent with the flat shape of accessory pinna part 12, but when the adjacent artificial feather 10a of shuttlecock overlaps with another feather, had the edge of uncoated reinforcement material in the inboard by that side of accessory pinna part 12 imbrication of another artificial feather 10.Therefore, compare with the situation that reinforcement material 15 is positioned on accessory pinna part 12 whole zone, weight saving.Fig. 6 has showed the external view of the shuttlecock 1a of the artificial person's hair 10a that uses the first embodiment.In this embodiment, 15 layers of face side that overlays on accessory pinna part 12 of reinforcement material.

In the artificial feather 10a of the first embodiment, the different layers shape of accessory pinna part 12 and reinforcement material 15 can greatly be improved durability and the impact absorbency of monolithic accessory pinna part 12, and not obvious obstruction loss of weight, and also have the flying quality of shuttlecock of further imitation natural feather and the effect of flight path.The performance of the shuttlecock of the artificial feather 10a that uses the first embodiment below will be described.

Fig. 7 A and 7B are the schematic diagram of the overlap condition of the adjacent artificial feather of displaying (10a and 10b).Fig. 7 A has showed the overlap condition of artificial feather 10b, this feather is used in the shuttlecock with the artificial feather 10b that is arranged in the whole lip-deep laminar reinforcement material 15 of accessory pinna part 12, and Fig. 7 B has showed the overlap condition of artificial feather 10a of the shuttlecock 1a of the artificial feather 10a that uses the first embodiment.Should be noted that in these Fig. 7 A, 7B, the state of illustrated artificial feather (10a and 10b) is the state when watching shuttlecock from the top.

At this, adjacent artificial feather (10a and the 10b) place of overlapping each other is made as overlapping region 30, and its not overlapping part is made as exclusive regional 40.In overlapping region 30, when between adjacent artificial feather (10a and 10b), when artificial feather that be positioned at the shuttlecock inboard (10a and 10b) is set as " inboard " of artificial feather (10a and 10b), the edge gross thickness that is positioned at two artificial feather 10b of overlapping region 30 becomes to use to have and is positioned at the twice of exclusive regional 40 thickness of shuttlecock that the whole lip-deep layer of accessory pinna part 12 covers the artificial feather 10b of reinforcement material 15, as shown in Fig. 7 A.Reinforcement material 15 is thicker than accessory pinna part 12, and the thickness difference between overlapping region 30 and exclusive regional 40 is compared with the shuttlecock of natural feather and become quite large.Namely, because the shuttlecock of natural feather has accessory pinna part that thin formation is only arranged (even in the overlapping region 30 be also like this), therefore, exclusive regional 40 and the thickness of overlapping region between difference formula minimum, thereby the thickness that makes skirt shape zone 4 roughly continuously and evenly.Yet, in the shuttlecock that uses the artificial feather 10b shown in Fig. 7 A, each artificial feather 10b has uniform thickness, wherein have layer and overlay on reinforcement material 15 on whole of accessory pinna part 12, and the thickness discontinuity of skirt shape part 4 becomes so obviously, to such an extent as to its flying quality and flight path will be different from the shuttlecock of natural feather.

In the shuttlecock 1 of use artificial feather 10a in the first embodiment shown in Fig. 7 B, the edge gross thickness of two inside and outside artificial feather 10a at 30 places, overlapping region is approximately equal to the thickness at exclusive regional 40 places.Or rather, be only the thickness of thin accessory pinna part 12.Therefore, for the shuttlecock 1 that uses the artificial feather 10a in the first embodiment, only have and to be the thin parts of accessory pinna part 12, and the thick parts that overlays on the reinforcement material 15 on each artificial feather 10a for layer, yet, skirt shape part 4 has roughly the same thickness as a whole, and this thickness is discontinuous in skirt shape part 4.For this reason, be contemplated to, flying quality and the flight path utmost point are like the shuttlecock of those natural feathers.

About the anterior-posterior relation of artificial feather 10a, in fact, reinforcement material 15 can be positioned at positive 13 sides, and accessory pinna part 12 can be positioned at positive 13 sides.Fig. 8 A and Fig. 8 B have showed the artificial feather 10c with the accessory pinna part 12 that is positioned at positive 13 sides, and the reinforcement material 15 that is positioned at the back side 14 sides.Fig. 8 A and 8B have showed when watching from the top, the adjacent artificial feather 10c of overlap condition.Fig. 8 A has showed a kind of state, the part that wherein overlays on the reinforcement material on accessory pinna part 12 without layer is stacked in the inboard under 30 places, overlapping region, and Fig. 8 B has showed a kind of state, wherein has a part that layer overlays on the reinforcement material on accessory pinna part 12 and is under 30 places, overlapping region in overlapping region 30 and is stacked in the inboard.

Like this, use the artificial feather 10a with the reinforcement material 15 that is positioned at positive 13 sides, accessory pinna part 12 is not directly impacted, as shown in above Fig. 7 B.Beyond all doubt ground, accessory pinna part 12 use the setting of non-weaving cloth can prevent that by strengthening coating fiber from disintegrating, and certainly, by reinforcement material 15 being placed in positive 13 sides, can prevent definitely that almost described fiber from disintegrating.In addition, can effectively prevent breaking of accessory pinna part 12, even if the base material of accessory pinna part 12 is not non-weaving cloth; By being placed in by the reinforcement material 15 that the foams of good shock absorbing capability are made positive 13 sides, the impulsive force when having avoided impacting is applied directly on accessory pinna part 12.

As shown in Fig. 8 A and 8B, artificial feather 10c with the accessory pinna part 12 that is positioned at face side, has good outward appearance, this is because reinforcement material 15 is positioned at rear side, and has the part that layer overlays on the reinforcement material 15 on accessory pinna part 12 and can't see from the shuttlecock outside without the difference in height between the part of laminar reinforcement material 15.In addition, should be appreciated that the shuttlecock that uses the artificial feather with the reinforcement material 15 on 14 sides overleaf, the shuttlecock 1 that has the artificial feather 10a that is positioned at the reinforcement material 15 on positive 13 sides with use is compared, and can prevent the generation that intersects.

Especially, as shown in the hollow arrow of Fig. 8 A and 8B, when impacting, 30 places are forced to positive 13 lateral bends to the parts that do not have laminar reinforcement material 15 of accessory pinna part 12 in the overlapping region.Although accessory pinna part 12 will shift to the right side-left to, and only when impacting in the front-back side direction, yet the part 15e at the edge of the reinforcement material 15 at 30 places, overlapping region supports accessory pinna part 12, has alleviated bending, as shown in the example of Fig. 8 A.In example shown in Fig. 8 B, a kind of state has occured, produced the interval that broadens between the accessory pinna part 12 at 30 places, overlapping region.Therefore, prevent the formation that intersects.No matter when, the front of artificial feather 10a-back side relation should correspondingly be determined by demand, that is, and and as outward appearance, durability, intersection possibility occurrence and the similar aspect of the shuttlecock of product.

Strengthen the weight of coating

As mentioned above, the artificial feather 10 that has the reinforcement coating that is formed on accessory pinna part 12 is determined to improve the shear strength of accessory pinna part 12 and shears percentage elongation.Use have the reinforcement material 15 that cut away in the overlapping region, 15 layers of shuttlecock that overlays on the artificial feather (10a and 10c) on accessory pinna part 12 of reinforcement material simultaneously, expection can have further improved durability, its flying quality can not descend simultaneously.

Next, research is used for improving the condition of durability and flying quality.Particularly, when being used to improve the durability of artificial feather (10a and 10b) as a large amount of resins of strengthening coating, the weight of monolithic artificial feather (10a and 10b) body will increase, and therefore, exist the possibility that flying quality descends.On the other hand, when the amount that reduces resin, when alleviating the weight of artificial feather (10a and 10b), durability will descend.In this situation first, the preparation per unit is used the various non-weaving cloths that the zone has the Different Weight soluble polyurethane, and measures the shear strength of every kind of non-weaving cloth and shear percentage elongation.In addition, preparation has layer and overlays on artificial feather 10c reinforcement material 15 on accessory pinna part 12 back 14 sides, that use above-mentioned various non-weaving cloths for the accessory pinna part, and lid artificial feather 10c arranges shown in Fig. 8 A, to make shuttlecock.Therefore, the flying quality of the durability of artificial feather 10c and shuttlecock is by the actual evaluation and test that impacts shuttlecock.In other words, impact the shuttlecock with the accessory pinna part 12 that is exposed to positive 13 sides in this evaluation and test mode, with its durability of evaluation and test and flying quality under the condition that is easier to damage at artificial feather 10c.

Notice, aspect durability, alternately impact shuttlecock 100 as two shuttlecock players of human observer, impact altogether 200 times at every turn, by the high clear strike, wherein shuttlecock is hit high strike far away, make accessory pinna part 12 be easy to damage.Therefore, by visual examination accessory pinna part 12, see whether produce fur on it and evaluate and test.

About flying quality, five shuttlecock players use well-known hairpin shot formula to impact the various shuttlecocks with different artificial feather structures as human observer, and can the evaluation and test shuttlecock controlledly fly with the path that is intended to along human observer.Particularly, use the shuttlecock that does not possess the artificial feather of strengthening coating to be set as reference value three minutes, the evaluation and test value is presented as three grades, one-level is that shuttlecock can't be controlled, secondary is that difficult is to control, three grades is that subjective evaluation and test is the same with reference value, adopts the mean value of five human observer as evaluation result.

Table 2 has been showed the reinforcement coating weight (g/m with respect to every cellar area ²) accessory pinna part 12 shear strength and shear percentage elongation, and the evaluation result of shuttlecock durability and flying quality aspect.In addition, table 3 has been showed the evaluation and test value to various shuttlecock flying qualitys that is drawn by five human observer.

[table 2]

[table 3]

The shear strength (N) of each and shearing percentage elongation (%) table 2 has been showed from sample a to i, and use sample a to flying quality and the durability evaluation result of the shuttlecock of i, wherein be made as sample a without the artificial feather that is formed at the reinforcement coating on accessory pinna part 12, and per unit area (g/m ²) eight kinds of dissimilar artificial feathers having applied different amount resins are made as sample b to i.Note, when the human observer A shown in table 3 to the average evaluation result of E be more than 1.0,1.5 when following, the flying quality comprehensive evaluating is " poor (POOR) "; When described result is 1, more than 5,2,5 when following, evaluates and tests and be " medium (FAIR) "; When described result be 2, more than 5,3 when following, evaluating and testing is " good (GOOD) ".Be placed in by/failed conclusion, if be suitable for actual use, shuttlecock be judged as by." medium " expression is when being used for exercise, and the flying quality of this shuttlecock can not throw into question, and " well " represents that the flying quality of this shuttlecock can make it be used for match.Therefore, table 2 has been showed the shuttlecock that uses such artificial feather 10c, and this artificial feather 10c has 1.8 g/m that use thereon ²And above reinforcement coating, and layer covers the reinforcement material 15 that the foams by being positioned on dorsal part 14 are thereon made, this shuttlecock can not produce fine hair, and has good durability, and, when the amount of the reinforcement coating of using is less than 27.0 g/m ²The time, flying quality is not cause in actual use the sort of grade of problem.

The reinforcement of the accessory pinna part of overlapping region

By this way, when worrying that part that layer not is covered with the accessory pinna part 12 of reinforcement material 15 lacks intensity, substitute the way that the shape of accessory pinna part the right or left side profile is cut, reinforcement material 15 can be made simply like this, make the part at its edge be cut off, extend to form towards the band shape of another adjacent artificial feather 10, thereby make the extension be used as the rib that supports membranaceous accessory pinna part 12.Fig. 9 has showed the artificial feather 10d with such mechanism, and wherein reinforcement material 15 comprises that layer overlays on the rib 15r on accessory pinna part 12.In Fig. 9, in shuttlecock, the setting of adjacent artificial feather 10d is shown as the state when watching from positive 13 sides or the back side 14 sides.The quantity of formed rib 15r shown in Figure 9 is two, but also can make one or three and more than.Should consider that all and intensity accessory pinna part 12 discontinuous due to the thickness at place, overlapping region causes the decline of flying quality when in any case, setting the width of rib 15r and quantity.

As shown in Figure 9, when the superficial layer that is arranged so that rib 15r as artificial feather 10d is relative with the superficial layer of adjacent artificial feather 10d, that is, when rib 15r was positioned at positive 13 side, artificial feather 10d was arranged on the back side 14 sides of the adjacent artificial feather 10d at 30 places, overlapping region.When rib 15r is positioned on the back side 14, namely be arranged on front 13 sides of the adjacent artificial feather 10d at 30 places, overlapping region as

rib

15r, 30 places will be in contact with one another in the overlapping region even if the difference in height between the surface of the surface of rib 15r and accessory pinna 12 will make two adjacent artificial feather 10d, 30 will form the interval in the overlapping region, when shuttlecock flies, air this interval of flowing through.In other words, the air stream when flight will can not get clogged, thereby reduce shuttlecock along the possibility of irregular path flight.

In addition, by utilizing the difference in height that is produced in the overlapping region by rib 15r, can be created in energetically the air-flow that flows through on direction from the bottom up.Figure 10 has showed the example of the artificial feather 10e of the rib 15r form with design.In this embodiment, bar shaped rib 15r tilts to extend from reinforcement material 15 towards adjacent artificial feather 10e from the bottom up.Like this, as shown in figure hollow core arrow, the rib 15r along this form tilts smoothly towards the upper reaches from the air of below, so that air stream is not interrupted, and generates the power that is used for making the shuttlecock rotation.Therefore, shuttlecock is along the path flight of imitating the natural feather ball.

The second embodiment

As mentioned above, when forming " intersection " in shuttlecock, it is difficult making intersection oneself return to its original state.In this case, the shuttlecock with this spline structure will be described as the second embodiment of the present invention, wherein intersect to be not easy to produce.Figure 11 has showed the state when the shuttlecock 1b according to second embodiment of the invention watches obliquely from the bottom.Figure 12 has showed the zoomed-in view the when part of the shuttlecock 1b of Figure 11 is watched from the top.This shuttlecock 1b comprises the artificial feather 10c shown in Fig. 8 A and 8B,, comprises artificial feather 10c that is, and this artificial feather 10c has the reinforcement material 15 that layer is overlying on the back side 14 sides.In this embodiment, the region division that does not have a laminar reinforcement material 15 is for 30 being exposed to positive 13 in the overlapping region.As described in Figure 11 and 12, wire adhesive member 60 penetrates every a slice artificial feather 10c simultaneously around skirt shape part 4 circulations of shuttlecock 1b.Note, the two ends of adhesive member 60 can or be pasted together and suitably fixed by tying-up.By this way, the shuttlecock 1b of the second embodiment has and is inserted between artificial feather 10c adjacent one another are, and adhesive member 60 is used for the generation that restriction intersects.In addition, the accessory pinna part 12 of each artificial feather 10c has the reinforcement coating of formation, thereby even if when applying strong impact force by impacting shuttlecock 1c to artificial feather 10c, accessory pinna part 12 can not begin to tear from the point that thin wire adhesive member 60 penetrates.In addition, pinna rachis part 20 will be can be crooked, its from 60 beginnings of wire adhesive member, be not wound around around pinna rachis part 20 as the circle segment of the strong point.

Note, when two ends of adhesive member 60 are fixed together, the chemical industry of conforming to the principle of simplicity is made angle, can consider two ends are tied up on pinna rachis part 20, even if yet this situation, except thereon that of end system with adhesive member 60, do not have the adhesive member 60 around its winding due to pinna rachis part 20, the end pinna rachis part 20 tied thereon with adhesive member 60 can freely move.Therefore, namely the two ends of convenient adhesive member 60 all tie up on pinna rachis part 20, and pinna rachis part 20 can be not crooked yet.In other words, be to be understood that, with have during adhesive member 60 lies in the adjacent artificial feather 10c of the artificial feather 1c of pinna rachis part 20, the structure of its pinna rachis part 20 does not have adhesive member 60 around the part of its winding, therefore, can not be wound with the problem of pinna rachis part 20 bendings of the end of adhesive member 60.

The 3rd embodiment

In a second embodiment, wire adhesive member 60 passes from artificial feather 10c simultaneously around skirt shape part 4, also prevents from intersecting.The third embodiment of the present invention is the shuttlecock that has be used to another structure that prevents from intersecting.Figure 13 has showed the shuttlecock 1c according to third embodiment of the invention when tilting to watch from the top.Figure 14 has showed the part of viewgraph of cross-section when the cutting of the chain-dotted line in Figure 13 shuttlecock.This shuttlecock 1 has the artificial feather 10f that belt is overlying on the reinforcement material 15 on accessory pinna part 12.Note, be similar to artificial feather 10a shown in Figure 6, have at this shuttlecock 1c that has showed the artificial feather 10f that belt is overlying on the reinforcement material 15 of positive 13 sides.

In the 3rd embodiment, artificial feather 10f has at upper and lower and extends upward the seam section 50 that is communicated with simultaneously front and back, and this seam section 50 is formed at the zone that is not formed with reinforcement material 15 on accessory pinna part 12.Penetrate the banded adhesive member 61 of seam section 50 around the skirt shape part 4 of shuttlecock 1c, and form annular by proper method, for example by the fixing end of adhesive member 61 of hot adhesion or adhesives.

Especially, adhesive member 61 at 30 places, overlapping region of adjacent artificial feather 10f internally the back side 14 of artificial feather 10c penetrate into positive 13 through seam section 50.And described adhesive member 61 penetrates the seam section 50 of the artificial feather 10c adjacent with associated inner artificial feather 10c.Therefore, adhesive member 61 continues to penetrate the overlapping region 30 of each artificial feather 10f, so that adjacent artificial feather 10f adheres to each other.

In the 3rd embodiment, namely box lunch be positioned at 30 places, overlapping region, be positioned at inside or outside artificial feather 10f by crooked and towards shuttlecock 1d biasing and when almost occuring to intersect, because adhesive member 61 continues to penetrate artificial feather 10f, therefore intersection is difficult to occur.As shown in figure 14, when being positioned at artificial feather 10f-1 30 places, overlapping region, that be positioned at the inboard at arrow F1 direction upper offset, produce frictional force when penetrating the seam 50-1 of section that is positioned at inboard artificial feather 10f-1 due to adhesive member 61, therefore, bonding firmware 61 is pulled on arrow F1, causes adhesive member 61 to be pulled on arrow F2 direction.Because adhesive member 61 also produces friction when penetrating the seam 50-2 of section that is positioned at outside artificial feather 10f-2, therefore, be positioned at outside artificial feather 10f-2 and have the power along arrow F2 that acts on seam section 50.And, have the pinna rachis part 20 that is connected to bottom 2 due to artificial feather 10f-2, therefore, artificial feather 10f-2 biasing is rotated on arrow F3 direction centered by pinna rachis part 20.Therefore, be positioned at inner artificial feather 10f-1 and make with the artificial feather 10f-2 that is positioned at the outside direction upper offset that both separates, thereby prevent assuredly that almost 30 places, overlapping region from intersecting.In addition, when being positioned at outside artificial feather 10f-2 at arrow F4 direction upper offset, 30 places against being positioned at inner artificial feather 10f-1, and making and are positioned at inboard this artificial feather 10f-1 at arrow F1 direction upper offset in the overlapping region to be positioned at outside artificial feather 10f-2.Therefore, prevent that in a similar manner intersection from producing.

Note, in the 3rd embodiment, adhesive member 61 is directed to the front 13 at 30 places, overlapping region, so that this adhesive member 60 is difficult to see from the outside of shuttlecock 1c.Therefore, also having a benefit is that the outward appearance of shuttlecock can not be affected substantially.Note, can use suitable materials such as resin molding or fibrous material as adhesive member 61, as long as its proportion is little.Used the non-weaving cloth identical with accessory pinna part 12 as adhesive member 61 in this example.By using the material identical with accessory pinna part 12, its permission shuttlecock has consistent outward appearance, and has successfully obtained the outward appearance that the utmost point is similar to the shuttlecock of natural feather.In fact, strengthening coating also can be formed on adhesive member 61.

In the shuttlecock 1e of aforementioned the 4th embodiment, the shape of accessory pinna part 12 itself has the inhibition of intersection structure.Therefore, need not to use wire or banded adhesive member (60,61), also need not the fixedly end of adhesive member (60,61)

Section, to form as the annulus of the second and the 3rd embodiment.Therefore, compare the second and the 3rd embodiment, saved the cost of adhesive member (60,61).On the other hand, the structure that suppresses to intersect can not eliminate the protuberance 70 that inserts when impacting again fall the possibility that from seam section (81,82) being used for of forming by protuberance 70 is inserted in seam section (81,82).Therefore, having a kind of protuberance 70 do not fall the structure that from seam section shuttlecock will be described as the 5th embodiment.

Figure 22 has showed the schematic diagram that suppresses structure according to the intersection of the shuttlecock of the 5th embodiment.The 5th embodiment uses the identical artificial feather 10h used with the 4th embodiment, and Figure 22 has showed that from the back side 14 are in the adjacent artificial feather 10h of overlap condition when watching.In addition, Figure 23 has showed along the viewgraph of cross-section of the line b-b in Figure 22.Similar to the 4th embodiment, the 5th embodiment has the most advanced and sophisticated 70a of the protuberance 70 that inserts through upper seam section 81, and described protuberance 70 14 guides to positively 13 from the back side, guides to the back side 14 sides from lower seam section 82 afterwards.Yet in the 5th embodiment, the most advanced and sophisticated 70a of the protuberance 70 that stretches out downwards from lower seam section 82 is bent upwards, and the most advanced and sophisticated 70a of protuberance 70 and bottom 70b are fixed as stratiform.

Note, protuberance 70 can be at first inserts through lower seam section 82, with inserting by upper seam section 81.In this case, the most advanced and sophisticated 70a of protuberance 70 can the layer be overlying on the bottom 70b front 13 sides.Further, in the 4th and the 5th embodiment, the intersection of description suppresses structure and has the artificial feather 10h that belt is overlying on the reinforcement material 15 on positive 13 sides, yet accessory pinna part 12 can be opposite with anterior-posterior relation between reinforcement material 15.

Fixed case

In the 5th embodiment, the most advanced and sophisticated 70a side and the bottom side 70b that are inserted in the L shaped protuberance 70 of two seam sections (81,82) fix, yet the shape of protuberance 70 is not limited to shown in this example.Below will provide the multiple fixed case of the 5th embodiment, wherein the shape of protuberance, seam section to form position or its direction that forms the place at place be different.

Figure 24 A and 24B have showed the fixed case of the 5th embodiment.Figure 24 A and 24B have showed to have the artificial feather 10i that layer is overlying on the reinforcement material 15 on the back side 14, and Figure 24 A has showed the plan view when watching from positive 13 sides, and Figure 24 B has showed the plan view when 14 sides are watched from the back side.Be formed on the right side-left linearly extended protuberance 71 that makes progress, it does not have the edge that layer is overlying on the part of the reinforcement material 15 on accessory pinna part 12 and is made as bottom 71b.Further, has seam section (83,84) in the zone that accessory pinna part 12 and layer are covered with reinforcement material 15, it is formed on the right side and left side of pinna rachis part 20, described each pinna rachis part upper-below extend upward, and be set parallel to each other, one is positioned at the right side, and another is positioned at the left side.

Figure 25 A and 25B have showed the schematic diagram that suppresses structure according to the intersection of the shuttlecock of this fixed case.The overlap condition view of Figure 25 A adjacent artificial feather 10i when watching from positive 13, Figure 20 B is 14 views when watching from behind.Further, Figure 26 A has showed along the cross-sectional view of the line c-c in Figure 25.In the embodiment shown, the most advanced and sophisticated 71a of protuberance 71 inserts through

left seam section

83,14 to guide to positively 13 from the back side, inserts from right seam section 84 afterwards, so that the most advanced and sophisticated 71a of protuberance 71 is guided to the back side 14 from positive 13.Further, the most advanced and sophisticated 71a of the protuberance 71 that stretches out from right seam section 84 is crooked left, and the most advanced and sophisticated side 71a of protuberance 71 and bottom 71b side are fixed as the laminar state.

Note, as shown in Figure 26 B, protuberance 71 can have most advanced and sophisticated 71a, and at first this tip 71a inserts through right seam section 84, inserts afterwards left seam section 83, is fixed as stratiform with rear tip 71a and bottom 71b.Further, as shown in figure 27, be formed with protuberance 71 and seam section (83,84) upper-each position that the below makes progress can change, and protuberance 70 and seam section (83,84) upper-lower relation can be opposite between adjacent artificial feather (10j-10j).Therefore, as the adjacent artificial feather 10j of square stance when the right side-left moves up, be applied to the right side-left to power different upper-produce on upper/lower positions.Therefore, this power is dispersed, and the most advanced and sophisticated 71a that is fixed together of protuberance 71 separates with bottom 71b, and the possibility that protuberance 71 breaks will reduce.

Other fixed case

Figure 28 A and 28B are for being used for the schematic diagram according to the artificial feather 10k of the shuttlecock of another fixed case of the 5th embodiment.Figure 28 A and 28B have showed respectively the plane diagram at front 13 and the back side 14 of artificial feather 10k.In these figure, 15 layers of the reinforcement materials of foams overlay on accessory pinna part 12, are below one and show that this armature bed of material is overlying on an example of positive 13 sides.As shown in Figure 28 A and 28B, in another fixed case of the 5th embodiment, the protuberance 72 of artificial feather 10k is not the L line, neither linear, but the form of approximate T shape, it stretches out to continue towards the left side, and branch out two tongues (72a, 72b) on above-below direction.Identical in seam section (85,86) and the 4th embodiment formed by two parts, and a seam section is positioned on another, and almost parallel each other, extends upward at the right side-left simultaneously.

Figure 29 A, 29B and 30 have showed the schematic diagram that suppresses structure according to the intersection of the artificial feather 10k of the 5th another fixed case of embodiment.Figure 29 A showed the adjacent artificial feather 10k that is in overlap condition when watching from positive 13, Figure 29 B showed its from the back side 14 views when watching.Figure 30 has showed along the cross-sectional view of the line d-d of Figure 29 A and 29B.In Figure 29 A, 29B and 30, when concentrating on a slice artificial feather 10k-1 when upper, the protuberance 72 of this artificial feather 10k-1 has the top 72a of branch, the upper seam section 85 of adjacent artificial feather 10k-2 on the left of this on, tongue is directed to, 14 to front 13 from the back side, and is bent downwardly.Lower tongue 72b is directed in the lower seam section 86 of the adjacent artificial feather 10k-2 in identical left side, and 14 to positive 13 from the back side, and be bent upwards.Further, the tip 73 of two of protuberance 72 tongues (72a, 72b) is fixed on the state that overlaps each other.

About the second to the 5th embodiment

The generation that the shuttlecock of the second and the 3rd embodiment (1b is to 1d) intersects with a kind of OILS STRUCTURE DEPRESSION, this structure has thin wire form or the adhesive member 60 of belt-like form, and it has the artificial feather of penetrating (10c, 10d, 10e, 10f) the certain width of accessory pinna part 12.In the 4th and the 5th embodiment, by being inserted, protuberance (70 to 72) is formed at the generation that suppresses to intersect in the seam section (81 to 86) of accessory pinna part 12.The second to the 5th embodiment has adopted a kind of structure, and it has the reinforcement coating that is formed on accessory pinna part 12, and this structure is the basic structure of the artificial feather 10 shown in the first embodiment.Therefore, even if shuttlecock penetrates with wire adhesive member 60 or banded adhesive member 61 or protuberance (70 to 72) pass respectively seam section (50,81 to 86) state is repeated to impact, accessory pinna part 12 will be not begin to tear from the end points place of the seam section (50,81 to 86) that wire adhesive member 60 penetrates or banded adhesive member 61 or protuberance (70 to 72) pass yet.In other words, by forming the reinforcement coating on accessory pinna part 12, realized that the intersection of use adhesive member (60,61) or protuberance (70 to 72) suppresses structure.

Further, wire adhesive member 60 penetrates accessory pinna part 12 at some place of the second embodiment, banded adhesive member 61 and protuberance (70 to 72) are inserted in the straight line seam section (50,81 to 86) that is formed on accessory pinna part 12 simultaneously, to suppress intersection in the 3rd to the 5th embodiment.Therefore, in the 3rd to the 5th embodiment, due to shuttlecock impacted with sudden force so that accessory pinna part 12 around some rotation as axle, accessory pinna part 12 will can not reversed.And the possibility that exclusive generation intersects for the example that uses wire adhesive member 60 is very low.

Especially, when using wire adhesive member 60, when obviously move when impacting on top too far away when its top around positional distance accessory pinna part 12 and accessory pinna part 12, the top of accessory pinna part 12 will be reversed, thereby will produce the problem of intersecting on the top of accessory pinna part, produce intersection even if penetrate at adhesive member 60 on the position at place.For example, when wire adhesive member 60 is used in the shuttlecock that uses the artificial feather that imitates natural feather, normally, when wire adhesive member 60 when the distance at position and accessory pinna part 12 tips is not in 18mm, because aforementioned accessory pinna part 12 is reversed the intersection that produces and probably occured.On the contrary, banded adhesive member 61 or protuberance (61 with width, 70 to 72) penetrate point-blank the accessory pinna part 12 of shuttlecock (10c is to 10k), accessory pinna part 12 is supported on the shuttlecock (1c in the third and fourth embodiment, 1d, 10e, 10f) and the 5th embodiment in the plane of shuttlecock in.Therefore, almost suppressed definitely the intersection that caused by the torsion of accessory pinna part 12.

In intersecting by the example that is suppressed as the wire adhesive member 60 in the second embodiment, the artificial feather 10c that forms shuttlecock 1b is supported by a point, this point allows artificial feather 10c freely to move on a definite level of this point, thereby makes flying quality be better than having the shuttlecock that the intersection of using banded adhesive member 61 and protuberance (70 to 72) suppresses structure.In fact, according to the shuttlecock of the second to the 5th embodiment, the movement of its accessory pinna part 12 is more easy, compares with the traditional shuttle that has around the wire adhesive member of the pinna rachis part 12 that will be wound around, and this has improved flying quality undoubtedly.

Further, when shuttlecock is firmly impacted, its thin line is as during the fulcrum when pinna rachis part 20 is wound around, existing the possibility that pinna rachis part 20 is broken at the wire adhesive member.Yet this possibility does not exist in a second embodiment, and this is only to pass the front and back of accessory pinna part 12 due to wire adhesive member 60.The banded adhesive member with width 61 that supports accessory pinna part 12 in the 3rd embodiment allows impulsive force to be dispersed, thereby makes the possibility of breaking of the pinna rachis part 20 that is caused by adhesive member 60 almost nil.Because the protuberance in the 4th and the 5th embodiment (70 to 72) does not extend through pinna rachis part 20, therefore, the breaking of pinna rachis part 20 that causes due to protuberance (70 and 72) can not occur in principle.
