Description
Technical field
The utility model relates to a kind of artificial feather for shuttlecock, and the utility model also relates to the shuttlecock that adopts this artificial feather to make.
Background technology
Adopt artificial material to replace natural goose duck feather to make the ideal that shuttlecock is industrial circle and badminton circle.Because the durable resistance of goose drake feather shuttlecock is too poor, causes the sportsman again and again to change the shuttle, and the cost of playing ball is improved greatly; Goose drake feather shuttlecock production technology cost numerous and diverse, material itself is also higher simultaneously.But the technical difficulty that this material replacement is hidden by no means common people can be imagined.Can find the sixties in last century from disclosed data just has the patent application of relevant artificial badminton, such as the clear 36-19067 that announces in clear and 36.10.12 (on October 12nd, 1961).More a little later, the patent application of free-standing artificial feather just there is the eighties in last century, such as the clear 57-177782 that announces in clear and 57.11.1 (November 1 nineteen eighty-two) etc.Industrial circle is carried out relevant research work and is surpassed 50 years, but up to the present, the shuttlecock that also replaces the goose drake feather to make without any a kind of artificial material reaches the level of high-quality goose feather shuttlecock in combination property.The nylon shuttlecock (also being plastic shuttlecock) of existing Integral ball skirt is although durable resistance is super good, and its combination property does not satisfy slightly good amateurish competitor's specification requirement of level at all, is abandoned by professional athlete especially.Until 2007, the artificial feather (abbreviation artificial feather) that is used for shuttlecock that just begins to occur having practical value; At the beginning of 2010, the shuttlecock listing of adopting artificial feather to make is arranged.But the shuttlecock that this employing artificial feather is made still exists overweight and the inadequate problem of rotary speed, does not still reach the level of high-quality goose feather ball fully.
Shuttlecock is that a finesse in football skills degree to the ball product requires very high product.The sportsman has turned out the very fine and smooth experience that impacts in long-term exercise and match.This natural goose feather ball experienced take high-quality of impacting is as the basis, comprises that weight, ball speed, rotation, high clear flight track, high clear flight stability, the stability of dropping shot, the rolling of chopping the chop, batting feel, batting turn one's head reaction speed, bat sound, accuracy in placement exactness, durable resistance etc.The artificial material shuttlecock be exactly will be on these factors as much as possible near natural goose feather ball.
The working condition of shuttlecock is extremely harsh, need to bear the unthinkable impulsive force of ordinary person.The striking speed of shuttlecock is the fastest at present all ball game, and the speed record that International Badminton Federation is admitted is 332 kilometers/hour, is created by Fu's Chinese athlete seapeak.And in informal match, then have the speed record that surpasses 400 kilometers/hour to occur.The amateur also can get the speed per hour more than 200 kilometers.Comparatively speaking, the speed record of tennis is 263 kilometers/hour that Australian personality Luo Si creates.The speed of baseball then is difficult to above 200 kilometers/hour.And later accelerate to again the most at a high speed from the percussion ball, often as long as some thousandths of second, this process, shuttlecock will bear the acceleration of tens G even up to a hundred G.Comparatively speaking, generally all at 20 below the G, the acceleration of manned space flight rocket is then generally in 10 G for the acceleration of Aero-Space rocket.Under with uniform velocity and acceleration condition, the wind resistance that the trumpet type ball bears than spheroidal ball can be larger; And the cantilever shape feather section of shuttlecock wants to bear so high acceleration and wind resistance, and its structural strength requires by no means that ordinary person can imagine.Natural goose feather plumage stalk has natural inside foam structure, and lightweight intensity is good, and its specific strength (mechanical strength under the equivalent weight condition) has surpassed present nearly all artificial material.Also this reason just, the Simulation Engineering of shuttlecock is gone through decades and is failed.
A standard natural feather bag is drawn together 16 feathers, and between 5.40 grams, this weight range is not to be the concept of allowable error to general whole ball weight, but under different height above sea levels or different atmospheric pressure different weight requirements is arranged at 4.74 grams.Center of gravity approximately drops near the coupling part of bulb and spheroid.Wherein: the weight of single workprint is below 0.13 gram, and the single weight of high-quality goose feather is about 0.10 gram.The gross weight of 16 feathers preferably is controlled at below 2.00 grams, and accessory pinna district (the comprising plumage stalk top) gross weight that wherein consists of windage ball skirt section generally will be controlled within 1.1 grams, be preferably between 0.90～1.0 gram.When the weight in ball skirt section point exceeded standard, the flying quality of shuttlecock will fast-descending.The accessory pinna of existing commercially available artificial badminton is relatively fitted by two foam sheets and is formed, and plumage stalk top is wrapped in the accessory pinna matrix.Single artificial feather weight surpasses 0.15 gram, and is heavy more a lot of than standard goose duck feather, so can only adopt 15 feather balls processed.Foaming accessory pinna gross thickness surpasses 1.5mm, and what have reaches 1.6mm.Although only have 15 feathers, the ball skirt section point gross weight of this artificial badminton has also surpassed 1.20 grams.In general, after ball skirt section point surpassed 1.10 grams, the flying quality of shuttlecock just greatly descended.What be exactly this very little 0.10 gram to 0.20 gram is overweight, affected shuttlecock flying quality---be mainly manifested in: (1) batting feel lays particular stress on; (2) the shuttlecock batting is later sluggish; Very easily roll when (3) dropping shot, unmanageable rollover phenomenon can occur during perhaps with racket top bead; (4) the high clear route is unstable.Above-mentioned these defectives just, although so that the sportsman is not ready to adopt this artificial badminton very much---its combination property has surmounted existing Integral ball skirt plastic shuttlecock far away, and its durable resistance has also surmounted common drake feather ball, and fundamental sum high-quality goose feather ball is suitable.
Affect the shuttlecock combination property, have seven large key elements at least: weight, distribution of weight, position of centre of gravity, spheroid support strength, positive wind resistance (or claiming axial wind resistance), around axle wind resistance and anti-fight endurance.Correspondingly just produce three large technical barriers: material closes, structure is closed and technique is closed.Any one of this seven large key element and three large technical barriers can not be up to standard, and shuttlecock just can not passive movement person be accepted, and also just is difficult to commercially achieve success.Therefore when whether a kind of shuttlecock new technology of examination is practical, comprehensively pass judgment on from above-mentioned seven large key element three disasters passes.In other words: slight shuttlecock is actually a system engineering, has comprised a plurality of subsystems, and is closely related between the subsystems, mutually restricts, influences each other, and the small adjustment of any one subsystem all can drive the change of total system combination property.Surpass the patent specification in 20 years from the span that retrieves, the overwhelming majority is the independent transformation for a certain subsystem, and mostly is based on theoretical imaginary design, without actual verification.So almost all do not have practicality or can't realize.Also this reason was just just gone through more than 50 years, by the end of 2007, occurred without any the novel badminton that has practical value except goose duck feather ball and the defective plastic shuttlecock of performance.
Contradiction between wherein wt, distribution of weight and the spheroid intensity is the most scabrous key element in the manually change process of present ball material.Shuttlecock is very responsive to the variation of weight, and its susceptibility reaches 0.1 grams magnitude, that is to say at some key positions, as long as the weight of 0.1 gram changes the great change that will cause the shuttlecock overall performance.And for the accessory pinna district of monolithic feather, the susceptibility of weight has then been reached 0.01 gram, and that is to say that if every feather increases by 0.01 gram, then near the reducing in whole ball skirt section adds 0.15 gram, such weight changes the flying quality with the heavy damage shuttlecock.The ball skirt section of existing plastic shuttlecock and artificial feather is point mostly overweight.The center of gravity of shuttlecock preferably drops near bulb and the spheroid connecting portion.If the skirt section is too heavy, move on the center of gravity, shuttlecock very easily rolls, and the closer to shuttlecock skirt section apical position, to overweight just quicker, because the moment of this position is maximum; If the skirt section kicks the beam, center of gravity too moves down, and then bulb tenesmus also affects performance.But on engineering, the weight in shuttlecock skirt section is more light better, because guaranteeing that the shuttlecock spheroid has that to do gentlyer under the prerequisite of enough support strengths be a high-leveled and difficult technical problem to product, and after having grasped ultralight skirt section manufacturing technology, carrying out again counterweight and then be easy to solve.Some artificial material shuttlecock is for loss of weight, just ball skirt pole make very carefully, the ball skirt does very thinly.Weight is up to standard, but insufficient strength, ball has not rotated yet.Whether shuttlecock can stablize rotation is very crucial.Being used for promoting shuttlecock around the axle wind resistance pivots.Shuttlecock when flight pivots not only can stablize its flight course, and can effectively consume the part kinetic energy that flies, and during by hard smash, certain decelerating effect is arranged at shuttlecock, makes its flying speed more meet the requirement of motion.
In addition, affecting the shuttlecock flying quality also has one not noted by the people, trickle, but very crucial factor: if the wind resistance jumping phenomenon---ball skirt support bar is too soft, then the shuttlecock skirt section drastic deformation can occur being impacted energetically moment, recover again immediately normal, process one of this contracting, wind resistance produces acute variation, make the shuttlecock flying speed produce the moment sudden change, the sportsman is the variation of imperceptible this speed perhaps, but flight and the standard badminton that can obviously realize shuttlecock are distinguishing---and go out feel of the ball feel and can become strange, drop point can be inaccurate.
With regard to spheroid intensity, always there is the extremely difficult contradiction that is in harmonious proportion between rigidity intensity, toughness and the weight---this character by material itself determined, in most cases, when a kind of rigidity strength enhancing of material, corresponding toughness will descend, and material can become fragile and not shock-resistant.Such as obstructing material for plumage, when promoting its rigidity, then corresponding toughness descends, and weight increases, and causes being interrupted with overweight easily.If adopt thinner plumage to obstruct to come weight reduction, then the support force of plumage stalk is not much of that again, thereby above-mentioned said wind resistance jumping phenomenon occurs.Equally, concerning accessory pinna, the accessory pinna both wings need preferably rigidity of support.When increasing accessory pinna thickness, can promote both wings rigidity of support and durable resistance, but can be overweight, thereby cause the shuttlecock performance sharply to descend.Otherwise when reduction thickness came loss of weight, then accessory pinna both wings rigidity of support and durable resistance were not much of that again, and the too low flying quality that can have a strong impact on shuttlecock of accessory pinna both wings rigidity of support.For existing artificial feather accessory pinna, in the situation that does not change thickness, can also adopt the method that improves its expansion ratio to come loss of weight, but this can cause accessory pinna both wings rigidity of support and durable resistance to descend in pairs equally.Existing artificial feather plumage stalk does not also reach the level of natural goose duck feather plumage stalk on rigidity intensity, weight is then slightly heavy than natural goose duck feather plumage stalk.Heavier many of the plumage silk of the natural goose duck feather of existing artificial feather accessory pinna weight ratio.And the accessory pinna alternative materials that intensity is enough, weight is lighter does not also occur.Can say,, whenever obtain one milligram loss of weight and all accomplish something difficult and so deserve praise particularly on the weight issue in accessory pinna district at artificial feather.
Thus, conditioning each other of the exploitation forever seven large key elements of artificial material shuttlecock, three large difficulties only considers that performance in a certain respect is not all right.More important and difficult is, any member of artificial feather ball is not simple engineering structure part, but when needs sustain the high speed HI high impact, can satisfy again the above-mentioned functor that impacts experience---comprise later more than ten functional imperative such as reaction speed, accuracy in placement exactness, durable resistance of weight, distribution of weight, position of centre of gravity, ball speed, rotation, high clear flight track, high clear flight stability, the stability of dropping shot, the rolling of chopping the chop, batting feel, batting sound, batting.And the association between these functional imperative and the structure mostly is recessive.Therefore all can not also can't go to pass judgment on mechanical support structure static state or macroscopic view or mechanical linkage relation simply for any architecture advances of artificial feather ball.
If can under the prerequisite that guarantees fundamental strength, find new alternate material or better structure to solve this 0.10 gram to the overweight problem of 0.20 gram, just can make undoubtedly the more excellent artificial badminton of performance.Solve route and have five at least: the one, set about from plumage stalk material; The 2nd, set about from the accessory pinna material; The 3rd, set about from the syndeton of plumage stalk and accessory pinna; The 4th, from the binding agent of accessory pinna set about (the present scheme, binding agent accounted for greatly the accessory pinna gross weight about 20%～30%); The 5th, set about from the structure of accessory pinna itself.So, whether does the end really exist feasible solution? which kind of technique direction is of the end that perhaps falls feasible? obviously all there is not ready-made answer! No. 2007100544123 patent specifications, this technical scheme is proposed and the sample that is made by handwork was totally pass by 5 years till now from May, 2007, although this technical scheme developer obtains certain progress at this technical barrier, but still fail fundamentally to solve this overweight defective; From this patent disclosure on November 19th, 2008 also past three year half till now, those skilled in the art's this defective of yet failing to solve; At the beginning of 2010, certain company of Japan formally releases the artificial badminton based on this technical scheme to market, pass by again two and half till now, still still fails to solve this defective again.
Because the accessory pinna part is the most responsive on the impact of artificial feather, therefore, a lot of technical staff are placed on research emphasis on the material or Structure Improvement in accessory pinna district.
The simplest method is the expansion ratio that directly reduces the thickness of accessory pinna or promote the accessory pinna foamed sheet, but the corresponding decline that all can bring durable resistance.If this method will have been seen the choice of properties of product---wish outstanding properties, then can sacrifice durable resistance, otherwise, if outstanding durable resistance then can be sacrificed performance.The dual lifting that wants in a word to obtain performance and durable resistance is the difficult again of difficulty.
In 2009801531378 these patent specifications of certain company's application, the technical staff proposes to arrange the method that stiffener promotes accessory pinna intensity.But only be provided with two very thin horizontal lines at accessory pinna in the commercially available prod of the said firm, other scheme is not all implemented.Although and two horizontal lines have slightly lifting (the lifting amplitude is very limited) to the durable resistance of accessory pinna both wings, but still can't solve the problem of Cracking of accessory pinna on plumage stalk contact wire.Other stiffener scheme in this specification can not solve the problem of Cracking of accessory pinna on plumage stalk contact wire equally, can make on the contrary overweight more outstanding.Therefore, this product have to adopt thicker accessory pinna in the hope of satisfying the durable resistance of basic demand---and the accessory pinna gross thickness of this product surpasses 1.5mm as previously mentioned, and overweight serious, also allows in appearance the people that clumsy sense is arranged, and lacks smart.
In 2010102914894 these patent specifications, mentioned and adopted the technical scheme that graticule mesh is set between two sheet materials.This specification thinks that graticule mesh is set like this can promote bonding strength between two sheet materials.In fact, graticule mesh not only can not promote the bonding strength between two sheet materials, can cause on the contrary the decline of trace.
In this patent specification of 201120229122X, the technical scheme that the technical staff has also proposed to arrange the flake reinforcement layer promotes the method for accessory pinna intensity, thereby can suitably reduce the thickness (similar with 2009801531378 technical scheme) of accessory pinna.Wherein also mention and adopt net to make enhancement layer.But actual tests shows that these common sheet enhancement layers have certain effect to the durable resistance that promotes the accessory pinna both wings, but still has no idea for solving the problem of Cracking of accessory pinna on plumage stalk contact wire.In this specification, it is general and occur easily misleading that the effect of net is described---this specification describes in the background technology final stage that " effect is not as cloth or flaky material on tamper-proof for latticed fabric, and particularly the effect of vibration-resistant destruction is less.But, latticed fabric slightly has superiority on weight ".It seems that now this conclusion is inaccurate, but in the fact misleading the utility model developer's a very long time.
In 2011204327527 these patent specifications, also the application on artificial feather is held a negating attitude to net.This specification is summed up at background technology part final stage: " when selecting latticed fabric as enhancement layer; although can suitably reduce the thickness of accessory pinna; obtain the weight loss effect on the weight; the limited humidification of its lifting is not enough to compensate the intensity decline that the accessory pinna thickness reduction causes, and the durable resistance of accessory pinna is descended.Therefore, latticed fabric is lost more than gain from performance as enhancement layer.Because the interrelated or mutual restriction between each systemic-function of shuttlecock emulation feather dedicated for badmintons, so that latticed fabric can not bring actual performance boost as enhancement layer, do not have a practicality.”。
Because above-mentioned misleading or the prejudice of net (or being graticule mesh), add net itself really to promote accessory pinna at the problem of Cracking at plumage stalk contact wire place almost without any effect, but also can cause the weight in accessory pinna district to increase, so this technical scheme cannot be applied always.Thus, the applicability of net on artificial feather strengthens always exists many misunderstandings and practical difficulty, can not produce positive enlightenment effect to synergistic application scheme of the present utility model.
In 2010102914894 these patent specifications, labor cause accessory pinna in the mechanism of action of plumage stalk contact wire place cracking, established theoretical foundation for addressing this problem.Cause this foaming accessory pinna to be two kinds of situations in the basic reason of plumage stalk contact wire place cracking: a kind of situation is that accessory pinna is directly impacted the destruction of being caused.When the feather sheet was hit by racquet frame, the foaming accessory pinna was sharply compressed by harder plumage stalk and racquet frame, and the plumage stalk is very thin, so this flashy pressure is very huge, accessory pinna will split along the contact wire with the plumage stalk.The second situation is to impact in the process normally, can tremble to the production high-frequency in plumage stalk top, and this trembling will damage to accessory pinna.The destruction of causing of trembling is cumulative, and from certain contact point of accessory pinna and plumage stalk, then slowly diffusion is until accessory pinna splits fully first.From the situation of reality test, the destruction of trembling is to cause accessory pinna from the main reason of plumage stalk contact wire cracking.When adopting thin slice enhancement layer or grid enhancement layer, the power of trembling can penetrate enhancement layer and through foaming layer, causes foaming layer to be ftractureed along contact wire.At this moment, just can not address this problem if adopt certain can extenuate material or the structure of trembling? fact proved that fillet shape foamed sheet or other similar puff can effectively be alleviated this high frequency and tremble.Method is exactly that fillet shape foamed sheet is covered on the plumage stalk, and plumage stalk top discord accessory pinna body is directly contacted.But the width of fillet shape foamed sheet again can not be too wide, too widely can lose effect again.Best when generally speaking, the both sides of fillet shape foamed sheet have just surpassed the width of plumage stalk itself.This fillet shape foamed sheet or other similar puff can be called buffer substrate tablet.
After adopting above-mentioned buffer substrate tablet technical scheme, just can reduce the thickness of accessory pinna body.Such as, the accessory pinna gross thickness of existing commercially available artificial badminton has surpassed 1.5mm, and what have reaches 1.6mm, and the accessory pinna expansion ratio is lower.And after the employing buffer substrate tablet, can the accessory pinna gross thickness be dropped to about 1.3mm, expansion ratio also slightly promotes simultaneously, and plumage stalk contact wire place is still not easy to crack.But, the accessory pinna district gross weight of 15 feathers (comprising part plumage stalk) has still approached 1.20 grams.This product with at present substantially unsuitable with the commercially available prod of buffer substrate tablet, slightly promotes on weight indicator on durable resistance.But on combination property, with standard badminton distance is arranged still.Further test is found, if adopt above-mentioned buffer substrate tablet and the further technical scheme that reduces accessory pinna thickness, the rigidity of support of artificial feather accessory pinna both wings is but weakened greatly, adjacent accessory pinna is easy to fit together, cause shuttlecock to descend around the axle rotating speed, even do not rotate fully, this performance to shuttlecock is flagrant; Simultaneously, the durable resistance of artificial feather also can descend.As if can say that existing artificial feather has excavated the potentiality of loss of weight or durable resistance ultimate attainment, more never again surplus can be compressed.
Because artificial feather is to the harsh requirement of weight, the developer is doing " subtraction " always by every means on the loss of weight engineering of artificial feather, wishes to reduce whatsit in the hope of the loss of weight benefit.As if larger breakthrough is tested and failed to obtain to a large amount of " subtractions ", and " subtraction " route has been gone to the end.Under having no alternative, the utility model developer determines to have a try " addition " again, and one of them is exactly to adopt to strengthen the coordination technique scheme that sheet cooperates buffer substrate tablet.In the fundamental test in early stage, overweight problem such as shadow and arrive, and more serious also can cause the bonding strength between accessory pinna two sheet materials to descend, and split before and after easily, and be often also poor than the scheme of simple enhancing accessory pinna thickness on resultant effect.No matter be to adopt the aforementioned nonwoven of introducing, lightweight adhesive tape or polyester pongee, be not always the case.The polyester pongee cloth generally all surpasses 25 gram/m
2, and nonwoven (containing a certain amount of glue) and lightweight adhesive tape are being lower than 20 gram/m
2, intensity is very poor.Adopt at last and originally think low weight and the bad net of enhancing effect, two accidents but impressively occur: the one, net is poor unlike nonwoven and lightweight adhesive tape to the enhancing effect of accessory pinna; The 2nd,, the weight of net does not resemble the so light of people's imagination.This has overthrown the saying in the 201120229122X specification basically.Be exactly mosquito net such as our the daily net that the most easily touches, and mosquito net with on the grammes per square metre of grenadine all at 30 gram/m
2About.The liner grenadine of common garment for children is also basically near 20 gram/m
2In general, if in accessory pinna liner net, its grammes per square metre can not surpass 15 gram/m
2, otherwise can have a strong impact on the shuttlecock overall performance, be preferably in 10 gram/m
2Below.Those skilled in the art are in daily life and work, and having few opportunities touches this ultralight net.And, be problematic in that: even if found this ultralight net, accessory pinna also will reduce thickness and come loss of weight with the weight gain of compensation net, is is not the rigidity of support of accessory pinna both wings and not much of that at this moment? in a word, the technological improvement of artificial feather, pull one hair and move the whole body, need system-wide unified the coordination.Because difficult, the enhancing loss of weight research of accessory pinna once had been absorbed in stagnation, the developer transfers to research emphasis on other member again.
In extremely accidental situation, the utility model developer has obtained a kind of ultralight net.So adopt thinner flexible foaming sheet material to make accessory pinna, adopt slightly thick flexible foaming sheet material to cook buffer substrate tablet, adopt this ultralight net to do and strengthen the collaborative buffer substrate tablet of sheet.Result of the test is all beyond one's expectations, and this cooperative approach not only very good, the weight of comprehensive durable resistance also meets the demands, most critical be that " rigidity of support " of accessory pinna both wings expected head and shoulders above.For this ultra-thin partially soft accessory pinna body, it is very poor that the developer estimated originally that the rigidity of support of accessory pinna both wings was bound to, and causes shuttlecock to rotate problem.But true really not so.After contrast contains net and do not contain the artificial badminton of net, finally find: originally, it is not merely the rigidity of support problem of accessory pinna both wings that the accessory pinna of artificial feather supports problem, and the elasticity that also relates to the accessory pinna both wings is recovered problem.In the situation that does not add net, the accessory pinna both wings just are difficult to recover straight after repeatedly being out of shape, and cause adjacent two accessory pinnas to be close to mutually.And after having added net, the accessory pinna both wings are because " tension " of net acts on, and always fast resilience keeps straight.After finding this point, will see further that this is similar with the characteristic of natural goose duck feather plumage silk exactly.Now observe the plumage silk of natural goose duck feather, we will notice that the support force of this plumage silk itself is not very strong again, but its resilience is fine, and fast resilience recovery of total energy makes the accessory pinna both wings always keep straight, until broken up fully after the distortion.
The ultralight net of so above-mentioned employing cooperates the synergistic application technical scheme of buffer substrate tablet, can be there there on the weight of accessory pinna what kind of impact actually? existing the overweight of commercially available artificial badminton accessory pinna is more serious, surpassed the loss of weight benefit that accessory pinna thickness descends and brings if increase the caused weight increase of said structure spare, then be merely disadvantageous in view of weight, then can affect the overall performance of shuttlecock, but also so that the production efficiency of artificial feather descends greatly, so just lost more than gain.Actual test shows that the artificial feather accessory pinna that adopts ultralight net to cooperate the cooperative approach of buffer substrate tablet to make is very excellent, as shown in table 1 at weight indicator.The expansion ratio of foamed sheet is higher than the summary of commercially available prod in 2# and the 3# product, so the weight of condition of equivalent thickness foamed sheet can be lighter.If reinforcement is not set, the higher then durable resistance of frothing percentage can be lower.And after adopting buffer substrate tablet and strengthen the cooperative approach of sheet according to the utility model scheme, it is very outstanding that the durable resistance of the accessory pinna that the thinner expansion ratio of thickness is higher remains, and gross weight is then than present commercially available prod 0.10 gram that descended.Because buffer substrate tablet has been arranged and has strengthened the protection of netting; the overall loss of weight potentiality of accessory pinna become very large once, can also further reduce thickness, foamed sheet such as accessory pinna and can also further improve expansion ratio, can also develop special-purpose larger lighter enhancing net of mesh etc.
Table 1:15 sheet accessory pinna integrated data
As seen, adopt the Ultralight net to cooperate the technical scheme of buffer substrate tablet, not only can promote the comprehensive durable resistance of accessory pinna, and can make accessory pinna do on the whole gentlyer, its lifting to the rigidity resilience of the accessory pinna both wings of attenuate then is all beyond one's expectations.In addition, the accessory pinna thickness reduction is to 1.0mm later in appearance also more close to the natural feather ball.The accessory pinna thickness of general goose drake feather (near plumage stalk place) is all between 0.8mm～1.0mm.
Accessory pinna is the easiest to be broken at place, trigonum, top, adds the consideration of weight, and it is just passable as long as cover the trigonum, top to it is generally acknowledged this lightweight net.But this lightweight net is also being born the elastic important task of lifting accessory pinna both wings rigidity, and therefore, its area of coverage just can not be too little.In general, the lightweight net will cover the over half of accessory pinna area at least, and effect person understands relatively good, preferably covers more than 2/3rds of accessory pinna area.
After a large amount of examinations of above-mentioned various artificial badmintons being packed the analysis summary, the basic law that accessory pinna breaks is finally gradually clear: do not adding in the situation of any protection, accessory pinna always small gap occurs at plumage stalk contact wire place first, then this breach is constantly accumulated expansion, can occur breaking at the outward flange of trigonum, accessory pinna top at last, rupture zone is expanded to the center then.And the mechanism of action of above-mentioned two kinds of failure modes is different, and the time sequencing of appearance is substantially fixing.The destruction of accessory pinna at plumage stalk contact wire place mainly is to cause owing to the plumage stalk trembles; And breaking appears in the outward flange of trigonum, accessory pinna top, then be since when flight high velocity air " tearing " cause the situation when being similar to a little flag and in wind, fluttering with mutually mutual friction between accessory pinna.
Before this, people only notice just that accessory pinna has been broken again, as for what break first wherefrom, how to break, and then seldom go to pay close attention to and analyze.In this case, when adopting various independent enhancement measures, one finds comprehensive durable resistance or bad or overweight, and just this enhancement measures of basic identification is inapplicable, then abandoned, then remove again to seek method for distinguishing.So often still merely to adjust accessory pinna thickness or to arrange as far as possible less and little reinforcement is dealt with.And these methods all are difficult to obtain the dual gain of durable resistance and loss of weight, and the combination property of shuttlecock is difficult to break through all the time, and before this, people do not recognize that also the shuttlecock performance also relates to rigidity resilience problem.The developer often can think: perhaps gone on the enhancing of accessory pinna and loss of weight and pushed up; again can not forward impelling, still lay stress on other member, try every possible means such as forwarding on the plumage stalk; such as the glue that uses still less, adopt for another example the method for hot pressing to replace glue with loss of weight.But these methods are difficult equally, and it is so easy not have.Also have the developer that research emphasis is placed in the enhancing and loss of weight of plumage stalk, the problem that they meet with is identical in fact---the restriction contradiction of bulk strength and weight is difficult to be in harmonious proportion.After they meet with setback, the same thought of will emerging: perhaps on the enhancing of plumage stalk and loss of weight, gone to and pushed up, again can not forward impelling, still lay stress on other member.Generally speaking, before any technical scheme makes a breakthrough, solve in the route five of above-mentioned enhancing losss of weight that provides, to have this directional problems of solution itself be exactly indefinite to which route actually.
Net is also better than frivolous materials such as nonwoven or adhesive tapes to the humidification of accessory pinna both wings.This point and our routine understanding are runed counter to: because observe above-mentioned various materials, we can find that net is pullled distortion even pulled loose than nonwoven and the easier quilt of adhesive tape.But after these materials were clipped in the middle by two sticking foam sheets of tool, reverse had appearred in situation---pressed from both sides the accessory pinna of net than the accessory pinna that has pressed from both sides nonwoven or adhesive tape more anti-ly on the whole pull, more tear-resistant.This may with the breach stress of material concentrate relevant, breach appears on nonwoven and the adhesive tape matrix and after, be easy to occur problem of stress concentration, cause breach to enlarge rapidly, then there is not this problem in net.Ex-post analysis; net may be such to the protection mechanism of accessory pinna: after the accessory pinna matrix has pressed from both sides net; accessory pinna just is equivalent to be divided into a plurality of block of cells, and then there is the fixing protection of the twine of net at the edge of each block of cells, so just break not quite easily.
The grammes per square metre of adhesive tape and polyester pongee cloth is generally all heavier, and being used for enhancement layer, particularly large tracts of land enhancement layer is that exhausted difficulty overcomes overweight problem.Nonwoven is then more special, and this material can be accomplished below 15 grams, but this moment, and it is anti-, and to pull tear-resistant strength ratio lower.And, also need to coat an amount of adhesive at material surface when adopting nonwoven to do enhancement layer, otherwise two foam sheets that consist of accessory pinna are easy to the front and back cracking.In this case, overweight problem highlights again.Then there is not this problem in net, can see through the mesh of net and mutually applying because consist of two foam sheets in front and back of accessory pinna.
The basic course of again combing artificial feather accessory pinna enhancing once of the below, loss of weight engineering, conveniently to understand the technical solution of the utility model:
1, initial product obtains preferably durable resistance with thicker foaming accessory pinna, but to sacrifice performance as cost;
2, repay the mode that the various sheetings of examination strengthen sheets and strengthen, but all can't resolve accessory pinna at the splintering problem at plumage stalk contact wire place, bring on the contrary more serious overweight.At this one-phase, find that net is poorer than the enhancing effect of other sheeting.This is because net there is not effect really on the shatter-proof execution of quivering, more very different than other sheeting.And the destruction of trembling is the failure mode that accessory pinna occurs at first.In fact, this one-phase people also do not understand fully the failure mechanism of trembling of accessory pinna, more do not know various ways and sequencing that accessory pinna destroys.
3, adopt buffer substrate tablet to solve accessory pinna in the destruction problem at plumage stalk contact wire place, and find the accessory pinna failure mechanism of trembling.The level of aggregation of performance and loss of weight is stepped a stage, but still have distance from high-quality natural feather ball.This one-phase, the total failure mechanism of the not clear accessory pinna of people is multiple, does not realize that also the accessory pinna both wings also relate to the rigidity resilience and recover problem except the rigid support problem, simultaneously, the applicability of net on accessory pinna strengthens is still had misunderstanding and prejudice.
4, break through inertial thinking, adopt the cooperative approach that increases net and buffer substrate tablet, obtained triple synergy that accessory pinna enhancing, loss of weight and rigidity resilience promote.Extra reinforcement but can bring the loss of weight benefit, reduces accessory pinna thickness or improves expansion ratio and but can bring the enhancing effect, and these all are that usual thinking is can't reasoning also unforeseen, more are not apparent.But in case point out, but seem so simple.In a word, probing into tera incognita, is phase alternating floor paper often, and when not grasping, total feel out of reach in case point out, is in fact stretched out one's hand and can visit.
The utility model content
In the utility model specification or claims, when relating to direction or orientation and describe, unifiedly follow following agreement: when relating to anyhow direction, be vertical with the parallel direction of plumage stalk 1,, it is horizontal obstructing vertical direction with plumage; When 2, relating to up and down the orientation, the accessory pinna direction is upper, and plumage stalk direction is for lower, and perhaps ball skirt direction is upper, and the bulb direction is for lower.
One of the technical problems to be solved in the utility model provides the more excellent artificial feather that is used for shuttlecock of a kind of performance.The technical problem that the utility model also will solve provides the more excellent shuttlecock of a kind of performance.
For solving the problems of the technologies described above, artificial feather for shuttlecock of the present utility model, comprise accessory pinna and plumage stalk, the top of plumage stalk is wrapped in the matrix of accessory pinna, it is characterized in that: the buffering covering that also is provided with the vertical strip that foam sheet makes on plumage stalk top, simultaneously, in the accessory pinna matrix, also be provided with the enhancing net that the lightweight net is made.Described buffering covering is used for slowing down the interaction force between plumage stalk and accessory pinna, is broken easily thereby the protection accessory pinna can not obstruct the contact wire place at plumage; Described enhancing net is used for promoting anti-destructiveness, resistance to tearing and the rigid support resilience pullled of accessory pinna both wings.
Described plumage stalk contact wire refers to accessory pinna and the overlapping strip zone of plumage stalk, the easiest centerline cracking in this strip zone of accessory pinna.The top thickness of existing artificial feather plumage stalk often only has a few tenths of a mm, and therefore such strip zone is also basically close to a line, so the utility model specification calls plumage stalk contact wire to this wire zone.
Described enhancing net occupies more than 1/2nd of described this bulk area of accessory pinna.Described enhancing net preferably occupies more than 2/3rds of described this bulk area of accessory pinna.The grammes per square metre that is used for the lightweight net of enhancing net generally is no more than 15g/m

The optimal material of making described buffering covering is the flexible foaming sheet material.
Generally speaking, when the both sides of vertical strip buffering covering had just surpassed the width of plumage stalk itself, the cushioning effect effect that plays was best.Based on the actual size situation of present artificial feather plumage stalk, the mean breadth of this vertical strip buffering covering is preferably between 1.0mm to 2.5mm.Dwindling of this width not only has the meaning that reduces weight, and the buffering humidification that the buffering covering is produced is more outstanding---and reason is, narrower buffering covering, itself just more is not easy to be derived from the destruction of trembling of plumage stalk.It is shorter that vertical strip buffering covering can be done, and only arranges in the accessory pinna upper end, also can do the same with the accessory pinna body longly, even surpass the length of accessory pinna body.Generally speaking, for the dual consideration of weight and buffering effect, the buffering covering length comparatively suitable between 8～20mm, take between 10mm～15mm for the best.
Described accessory pinna is relatively to be fitted by two flexible foaming sheet materials to form, and the gross thickness of accessory pinna both wings is less than 1.1mm.More precisely, the accessory pinna body is wrapped in plumage stalk top by the two flexible foaming sheet materials in front and back and forms, and the gross thickness of accessory pinna body both wings is preferably in below the 1.1mm, particularly below 1.0mm.Otherwise can cause the accessory pinna district integral body of artificial feather overweight, thereby affect the overall performance of shuttlecock.
A slice buffering covering, respectively two flexible foaming sheet materials of protection structure accessory pinna can respectively be set before and after the plumage stalk.That is to say, on plumage stalk top 2 buffering coverings can be set.The enhancing net of being made by the lightweight net is as long as one deck is just passable, certainly, if the weight conditions permit also can be done two-layer, even more multi-layered.
As long as technique and weight all allow, the fluff material of other type also can be used for making the buffering covering, such as unbodied expanded material, cotton-wool etc.Be expressed as: a kind of artificial feather for shuttlecock; comprise accessory pinna and plumage stalk; the top of plumage stalk is wrapped in the matrix of accessory pinna; it is characterized in that: plumage stalk top also includes the buffering covering that fluff material is made; described buffering covering is used for slowing down the interaction force between plumage stalk and the accessory pinna; thereby the protection accessory pinna can not obstruct the contact wire place at plumage and be broken easily; simultaneously; in the accessory pinna matrix, also be provided with the enhancing net that the lightweight net is made, be used for promoting anti-destructiveness, resistance to tearing and the rigid support resilience pullled of accessory pinna both wings.
Elongate in shape described in the utility model claims and the specification might not be regular rectangle.This elongate in shape both can be that periphery is smooth rectangular, also can be that the irregularity of both sides undulate or other shape is rectangular.Even deliberately add several list edges on rectangular both sides, and also have same effect, therefore also still belong to protection domain of the present utility model.
The technical problem that the utility model also will solve provides the more excellent shuttlecock of a kind of performance.For solving the problems of the technologies described above, shuttlecock of the present utility model comprises artificial feather, it is characterized in that, what described artificial feather adopted is above-mentioned artificial feather for shuttlecock.Ball making method can adopt the technique same with the natural feather ball.In order to prevent that the accessory pinna that order laminates from being upset, can be at 1 road, ball skirt position or several roads set winding of this shuttlecock.
With respect to the existing artificial feather that is used for shuttlecock, artificial feather weight of the present utility model more meets standard, intensity is better, and durable resistance is very high, and the deformation resilience ability of accessory pinna is closer to natural feather, on performance, reach the level of common goose duck feather fully, approached the high-quality goose feather.The advantages such as the shuttlecock of being made by this artificial feather has that flying quality is good, batting soft handle, durable resistance are good make the artificial material shuttlecock further approach high-quality goose feather shuttlecock in combination property, then are better than the natural feather ball on durable resistance far away.
