Abstract

The invention relates to a shuttlecock made from a lightweight and elastic material. A spherical crown is made from the lightweight and elastic material in a shape similar to the appearance of a spherical crown of a conventional shuttlecock, and the lightweight and elastic material can be also implanted in the spherical crown to make a bracket, so as to play roles in promoting structural strength and carrying out counterweight adjustment on overall mass distribution. The shuttlecock made from the lightweight and elastic material is directly made from the lightweight and elastic material such as expandable polyethylene (EPE), expandable polystyrene (EPS) and the like in the shape similar to that of the spherical crown of the shuttlecock, and the weight distribution of the shuttlecock made from the lightweight and elastic material is enabled to be also similar to that of the conventional shuttlecock. The novel shuttlecock provided by the invention has the appearance and the mass distribution, which are similar to those of the conventional shuttlecock, and therefore, the novel shuttlecock and the conventional shuttlecock have similar flying performances. However, as the spherical crown of the novel shuttlecock is made from the lightweight and elastic material, the shuttlecock made from the lightweight and elastic material is resistant to playing and difficult to break and damage, and compared with the conventional shuttlecock, is obviously prolonged in service life. Meanwhile, the manufacturing flow of the novel shuttlecock is simpler; the used material is cheap in price; the manufacturing cost can be effectively reduced.

Description

A kind of shuttlecock adopting light elastic material to make

Technical field

The present invention relates to a kind of shuttlecock adopting light elastic material to make.

Background technology

Badminton suits the taste of both old and young, be at home popularize very much, a very welcome sports events, shuttlecock demand at home and consumption all very large.The expense buying shuttlecock is one of capital cost of badminton, accounts for more than 1/3rd of totle drilling cost.Traditional shuttlecock is all be woven into spherical crown with the goose feather plumage pruned or duck tail feather plumage, then be connected to and ball holder is made, cost is high, and the feather of ball is easy to the damage that fractures in the process by racket impact, cause the service life of traditional shuttle too short, add the cost of badminton.

For this reason, shuttlecock manufacturer is all striving to find the substitute of shuttlecock, but be all utilize material to go to imitate and alternative feather, as the imitated shuttlecock of the models such as Mavis350 and Mavis500 that YONEX company produces, be have employed the synthetic materials such as nylon to imitate feather, thus make imitated nylon shuttlecock.But because imitated feather is very difficult consistent with the character of true feather, make this material copy feather and the shuttlecock made does not reach performance with the made shuttlecock of true feather, imitated shuttlecock is not widely applied.The plastic shuttlecock that in Chinese market, also useful plastics are imitated, namely the shape of shuttlecock spherical crown is simulated with plastic material, although price is cheap, but draw up next spherical crown compared with true shuttlecock spherical crown with Mold for Plastics, its Mass Distribution and structural strength all differ greatly, make plastic shuttlecock not reach the flying quality of true shuttlecock far away, the feel of square stance is very poor, uses seldom so actual.

Summary of the invention

For solving the problem, a kind of light elastic material such as sponge or foam that adopts of special proposition is the shuttlecock that main material is made.Due to the imitated difficulty of feather, so the present invention is different from other removes to simulate and replace feather thinking with material, but the direct material of proposition is made into the imitated shuttlecock similar to traditional shuttle monnolithic case, thus has avoided this difficulties of imitated feather.

Adopt the shuttlecock that light elastic material is made, comprise spherical crown 1 and ball holder 2, be firmly connected with ball holder 2 bottom described spherical crown 1.

Described spherical crown 1 adopts the light elastic material such as sponge or foam to make the shape consistent with traditional shuttle spherical crown profile, and makes the overall weight of novel badminton and Mass Distribution all consistent with traditional shuttle by the density controlling material with global shape.Flying quality due to shuttlecock is mainly subject to the impact of its Mass Distribution and aerodynamic configuration, so novel badminton only needs its profile consistent with traditional shuttle with Mass Distribution, just can ensure that novel badminton has the identical flying quality of traditional shuttle.

Can also insert in described spherical crown 1 and make support with lightweight elastic-plastic material, the effect of counterweight adjustment is carried out to play lift structure intensity and to distribute to total quality, the structural strength of novel badminton is distributed roughly the same with traditional shuttle with Mass Distribution, allow novel badminton consistent with traditional shuttle by feel during racket impact.

Described spherical crown has the profile consistent with traditional shuttle, and its external diameter is reduced to bottom gradually by spherical crown top, as spherical crown external diameter linear change type, the middle slightly convex of spherical crown and the middle slightly matrix of spherical crown.The traditional shuttle profile slightly difference of different ball speed, when the subtended angle of its spherical crown is larger, ball speed is slower, so novel badminton also can control by the profile identical from traditional shuttle the shuttlecock making different ball speed.

Described spherical crown has the profile consistent with traditional shuttle, and its cross section is Rotational Symmetry figure, as circle, regular polygon, annular, petal, garland shape etc.; Fig. 3 respectively show a kind of pattern of annular, petal, garland shape.

Firmly be connected with ball holder bottom described spherical crown, or the part bottom spherical crown implanted ball holder and firmly connects.When there being support, frame bottom can directly and ball holder strong bond, also frame bottom can be implanted ball holder and with ball holder strong bond.

This patent is not go simulation with material or replace feather, but with the light elastic material such as sponge or foam, as expanded polyethylene foam (EPE), Poly Foam (EPS) etc., directly make the shape consistent with shuttlecock spherical crown monnolithic case, and make its distribution of weight also roughly the same with traditional shuttle by means such as density of material control, shape controlling and support counterweights.Because the novel badminton of invention has consistent profile and roughly the same Mass Distribution with traditional shuttle, so both can have similar flying quality.But spherical crown made by the material that have employed lightweight flexible due to this kind of novel badminton, beat, not easily lose so resistance to, for traditional shuttle, its service life can obviously increase.The Making programme of novel badminton is more simple simultaneously, and the material price used is cheap, effectively can reduce cost of manufacture.In sum, the novel badminton of invention is owing to possessing the price advantage of resistance to performance advantage of beating and angle simultaneously, and can obviously reduce badminton cost, application prospect is boundless.

Detailed description of the invention

A kind of concrete embodiment:

Adopt expanded polyethylene foam (EPE) material to make the novel badminton of circular platform type spherical crown, make its monnolithic case consistent with traditional shuttle profile, as shown in Figure 8.Roundlet cone space can be reserved, to alleviate the weight at spherical crown top in the middle of round platform.

Adopting TPEE(thermoplastic polyester elastomer) material makes tree-like support, as shown in Figure 9, to be placed in the middle of spherical crown and strong bond.

The preparation method of ball holder can be identical with traditional shuttle, and adopt cork balling-up holder, outside dermatine wraps up.By bonding according to the sound construction shown in Figure 10 to spherical crown, support and ball holder, make a kind of novel badminton described in this patent.

the profile defining method of novel badminton

The shuttlecock of selected a fixing ball speed, as with reference to object, obtains the curvilinear equation f changed with height h with reference to shuttlecock external diameter r by repetitive measurement

Wherein, height h for reference zero, is up positive direction to spherical crown top with ball holder top.

After obtaining the change function of reference shuttlecock external diameter with height, namely can determine the external diameter R of novel badminton with height change.Because the air drag properties on different materials surface is not identical, so in order to obtain the aerodynamic characteristic identical with traditional shuttle, external diameter R also needs certain correction with height change , namely

Correction can be determined by a large amount of actual experiment.

the defining method of the density of material of novel badminton

The shuttlecock of selected a fixing ball speed, as with reference to shuttlecock, obtains the curvilinear equation g changed with height h with reference to shuttlecock quality m by repetitive measurement

After obtaining the change function of reference shuttlecock quality with height, namely can determine the change curve equation of the mass M of novel badminton with height, need equally to add correction

Correction can be determined by a large amount of actual experiment equally.It should be noted that the quality of now novel badminton spherical cap portion is determined jointly by spherical crown and support, so can by controlling the density of spherical crown material or controlling the shape of support and density makes the quality of its differing heights meet above-mentioned requirements.
