Abstract

The utility model relates to an artificial feather dedicated for a shuttlecock, which comprises a feather sheet (11) and a feather stem (12). The artificial feather is characterized in that the longitudinal edge of the waist part of the feather stem (12) is provided with inverted teeth (121) or barbs (122). During the manufacturing of a shuttlecock made of the artificial feathers, a coil at the waist part of the shuttlecock is prevented from sliding downwards through the inverted teeth (121) or the barbs (122). A concavo-convex structure (123) or notches arranged at the longitudinal edge of the waist part of the feather stem (12) can play the same role. The utility model also relates to a shuttlecock made of the artificial feathers.

Description

The special-purpose artificial feather of shuttlecock reaches by its shuttlecock of processing

Technical field

The utility model relates to the special-purpose artificial feather of shuttlecock, and the utility model also relates to the shuttlecock that adopts this artificial feather to process.

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 to change the shuttle again and again, 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 common people by no means can be imagined.Industrial circle is carried out relevant research work and is surpassed 20 years, but up to the present, the shuttlecock that also has no a kind of artificial material to replace the goose drake feather to process reaches the level of high-quality goose drake feather shuttlecock on combination property.The combination property of existing plastic shuttlecock has satisfied not level good amateurish competitor's specification requirement slightly at all, is abandoned by professional athlete especially.Up to 2007, just begin to occur having the dedicated emulated feather of shuttlecock (being called for short the emulation feather) of practical value; To the end of the year 2009, the shuttlecock listing of adopting the emulation feather to process is arranged.But the shuttlecock that this employing emulation feather is processed still exists rigidity intensity to show not enough or overweight problem slightly, 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 article requires very high product.The sportsman has turned out the very fine and smooth experience that impacts in long-term exercise and match.Thisly impact experience and be the basis, comprise weight, ball speed, rotation, high clear flight track, the stability of dropping shot, chop the chop and roll, bat feel, batting sound, accuracy in placement exactness or the like with the natural goose feather ball of high-quality.The artificial material shuttlecock be exactly will be on these factors as much as possible approaching natural goose feather ball.

Influence the shuttlecock combination property, have seven big 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 big technical barriers: material closes, structure is closed and technology is closed.Any one of this seven big key element and three big technical barriers can not be up to standard, and shuttlecock just can not passive movement person be accepted, and also just is difficult to achieve success commercial.Therefore when a kind of shuttlecock new technology of examination is whether practical, carry out multifactorial evaluation from above-mentioned seven big key element three disasters passes.In other words: slight shuttlecock is actually a system engineering; Comprised a plurality of subsystems, tight association between each sub-systems influences each other; The small adjustment of any one subsystem all can drive the change of total system combination property---such as between spheroid support strength and the weight being the most difficult a pair of contradiction that is in harmonious proportion; When promoting intensity, will be overweight, intensity is not much of that again when weight reduction.Surpass the patent specification in 20 years from the span that retrieves, the overwhelming majority is the independent transformation to a certain subsystem, and mostly is based on theoretical imaginary design, without actual verification.So almost do not have practicality all, perhaps can't realize.Also this reason just, just go through 20 surplus year, by the end of 2008, except goose duck feather ball and the defective plastic shuttlecock of performance, have no the novel badminton appearance of tool practical value.

Wherein wt, distribution of weight and rotation are the most scabrous key elements in the present ball material manual workization process.Shuttlecock is very responsive to the variation of weight, and its susceptibility reaches the 0.1 gram order of 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, the susceptibility of weight has then been reached 0.01 gram for the monolithic feather, and that is to say that if every feather increases by 0.01 gram, near the reducing in then whole ball skirt section adds 0.15 gram, such weight changes the flying quality with the heavy damage shuttlecock.The ball skirt portion of existing plastic shuttlecock and emulation feather is mostly overweight.The center of gravity of shuttlecock preferably drops near bulb and the spheroid connecting portion.If the skirt section is too heavy, upper shift of gravity center, shuttlecock very easily rolls, and the closer to the shuttlecock skirt section apical position, just big more to overweight susceptibility 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 influences performance.But from engineering; The weight in shuttlecock skirt section is more gently good more; Because do product to such an extent that gentlier be a high-leveled and difficult technical problem under the prerequisite of enough support strengths guaranteeing that the shuttlecock spheroid has, and after having grasped the skirt section manufacturing technology of ultralight, carry out counterweight again 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 flight the time is pivoted and not only can be stablized 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; Influencing the shuttlecock flying quality and also have that do not noted, a trickle but The key factor very: if the wind resistance jumping phenomenon by the people---ball skirt support bar is too soft; Then the shuttlecock skirt section drastic deformation can occur being impacted moment energetically, recovers normal immediately again, in this process of one of 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 shuttlecock that can obviously realize shuttlecock are distinguishing---and go out can become strange, drop point of feel of the ball feel and understand inaccurate.

Thus, the exploitation of artificial material shuttlecock faces conditioning each other of seven big key elements, three big difficulties forever, only considers that performance in a certain respect is not all right.All need evaluate and test again the trickle improvement in any point of artificial shuttlecock, often be difficult to whether feasible with a certain improvement project of intuitive judgment simply from the combination property of whole system.Yet therefore feasible any trickle improvement to artificial shuttlecock is not so conspicuous.

In the artificial material shuttlecock, adopting independent artificial feather system ball is a most important branch.All relate to artificial feather such as following patent documents: 85108694,2007100544123,2008800014168,2009801359076,2011200715788 etc.

Occurred the shuttlecock that a kind of artificial feather is made now on the market, this shuttlecock is very anti-to be beaten.But, also have some shortcomings, such as, the loosening easily and downslide of the coil of this artificial shuttlecock makes the shuttlecock distortion.The artificial feather of this shuttlecock is made up of pinna rachis and accessory pinna, and pinna rachis adopts nylon to process.Because the surperficial opposed flattened of nylon pinna rachis is smooth, adds that whole spheroid is a kind of cone shape, and is up big and down small, shuttlecock is receiving when impacting, and the coil that is positioned at waist is easy to loosening and glides, and seriously influences the flying quality of shuttlecock.The people who is skillful in badminton knows that when smash, the impulsive force that shuttlecock receives is very big, and in this case, the best glue of bonding force can not guarantee the firm of coil.

In 2009801359076 and 2011200715788 patent specifications; Introduced a kind of processing scheme: flexure member is set on the surface of pinna rachis---so-called flexure member be exactly after distortion not can the restorable member of resilience---coil obtains bigger contact area through pushing this flexure member, thereby the lifting bonding force.This flexure member comprises two kinds of situations, and a kind of prolongation tail and pinna rachis that is the accessory pinna bottom extends out links together, and coil is wrapped in their outside again, makes the binding strength that prolongs the tail distortion and promote coil and pinna rachis; Another kind of material by pinna rachis itself constitutes; Method is that the longitudinal edge along pinna rachis is provided with softer thin-walled relatively; Push this thin-walled when coil is wrapped in the top and make its distortion, with the contact area of increase coil and pinna rachis, thus the binding strength of lifting coil and pinna rachis.In case of necessity, this scheme also is provided with some convexities or recess at described flexure member edge, with contact area, the adhesive strength of further increase coil (knitmesh restiform bodies) and flexure member.And in fact, because the impulsive force that the shuttlecock smash time is born is very huge, the lifting of this limited connection power is of no help with thing, can not fundamentally solve the pine cunning difficult problem of coil and pinna rachis.In other words, this flexure member can promote the adhesive strength between coil and the pinna rachis to a certain extent, but the lifting of this intensity is very limited; Importantly this flexure member can't solve the loosening downslide problem afterwards of coil.

So,, perhaps become the pinna rachis edge designs thorn point to point to the hangnail structure of accessory pinna direction if the concavo-convex pawl structure of pinna rachis edge designs engrail, just can not address this problem? In fact this design is exactly the hair stubble that has imitated natural feather.We can observe, and the Lower Half of natural feather after cutting off the feather silk, stays any mao stubble.This residual hair stubble can help the connection between coil and the pinna rachis more firm, prevents that coil from gliding.This pawl of the utility model or hangnail upwards " top " are lived coil, have effectively dissolved the power of pullling that acts on the coil downwards, thereby have protected the syndeton between coil and the pinna rachis not to be destroyed.This effect is that above-mentioned flexure member is not available.

Overweight for fear of artificial feather, can only be designed to above-mentioned pawl or hangnail structure to the pinna rachis local edge of coil position.Even can a pawl or hangnail only be set whole pinna rachis.But only be provided with a pawl or hangnail confirm in the position on difficulty very because when the system ball, the bore of shuttlecock mainly moves up and down the position through coil and regulates.The concrete group of number and the number of pawl or hangnail will be set according to the weight and the action effect of reality.

The cross section of the pinna rachis of existing artificial feather is " ten " font, both can pawl or hangnail structure all be set at four edges of " ten " word, and also one or two edge is provided with pawl or hangnail structure therein.After processing shuttlecock, be positioned at the pawl of the inside and outside both sides of pinna rachis or the on-slip effect of hangnail structure and be greater than pawl or the hangnail structure that is positioned at the pinna rachis left and right sides.The shape of cross section of pinna rachis is not limited to " ten " font, and for the pinna rachis of other shape of cross section, above-mentioned pawl or hangnail organization plan are suitable equally.

In general, shuttlecock comprises twice waist coil, and wherein upper track coil (near the waist coil of accessory pinna) is being born more important role, and its destructive power of bearing is also bigger.So,, can only pawl or hangnail be set to the upper track coil from the consideration of Weight control.

Above-mentioned pawl or hangnail are preventing that coil effect loosening or that glide from being best.

In general, the rigid member of concaveconvex structure can play essentially identical effect, and particularly the effect of zigzag concaveconvex structure is comparatively obvious.Such as the rigid member of semi-cylindrical hill, and the rigid member of the semi-cylindrical hill of continuous a plurality of arrangements can play the effect that prevents that coil is loosening or glide well.Increase the scheme of contact area with respect to the distortion of available technology adopting flexure member; Adopting the main distinction of rigid member is exactly the support force that necessarily makes progress to be provided to coil; Thereby all or part of counteracting acts on the downward power of pullling on the coil when impacting, the syndeton of protection coil and pinna rachis is not destroyed.So-called rigid member is exactly not yielding or can the restorable member of resilience after distortion.

Compare prior art,, following two much progresses are arranged by the shuttlecock that the artificial feather of the utility model is processed: the one, the coil firmness promotes significantly, is difficult for loosening; The 2nd, the pawl or the hangnail structure of employing the utility model even if becoming flexible appears in the waist coil, can not glide yet, thereby have guaranteed the stability of the global shape and the bore of shuttlecock.Therefore, the shuttlecock flight stability of the utility model is better, and durable resistance is higher.And the technology that realizes this structure is also very simple, can not increase extra cost.

The utility model content:

One of problem that the utility model will solve is to provide a kind of shuttlecock special-purpose artificial feather, and another technical problem that the utility model will solve provides the shuttlecock of being processed by above-mentioned artificial feather.

The utility model is followed following provisions when relating to above-below direction or interior exterior orientation: the accessory pinna direction is last, and feather root direction is down; Perhaps the ball skirt direction of shuttlecock is last, and the bulb direction is for down, in the direction of pointing to the central shaft of shuttlecock is, otherwise outside being; The direction parallel with pinna rachis is that vertically the direction that each pinna rachis is vertical is horizontal.

For solving the problems of the technologies described above, the special-purpose artificial feather of the shuttlecock of the utility model comprises accessory pinna and pinna rachis, it is characterized in that the waist longitudinal edge of said pinna rachis is provided with pawl or hangnail.This manual work feather is when processing shuttlecock, and said pawl or hangnail can prevent that the waist coil of shuttlecock from gliding.
