The utility model relates to shuttlecock, a kind of energy windproof badminton structure of saying so exactly.

Background technology

Shuttlecock is taken exercises one of used daily apparatus as people, has huge advantage, and its reason is that the use of shuttlecock is not limited to specific place, as long as a secondary racket, a shuttlecock are arranged, people just can move in the place of spaciousness.So badminton is very popular.

The shuttlecock of Xiao Shouing mostly is indoor ball greatly in the market, and quality is lighter, is fit to use in the indoor feather arena.Yet for the people of China's great majority participation badminton body-building, they mainly play badminton on the ground at outdoor barnyard.But outdoor, under most of situation wind is arranged, can be subjected to the influence of wind when playing badminton.In order to offset the resistance of outdoor wind, make the shuttlecock heading comparatively stable, the weight of outdoor shuttlecock lays particular stress on usually.Wherein, the outdoor shuttlecock that Shanghai shuttlecock factory produces, except gaining in weight, also adopted elasticity elastomeric material preferably in the ball holder, the bigger impulsive force of generation in a flash that shuttlecock is being contacted with racket, thereby make the shuttlecock that launches away that ball speed faster arranged, obtained stronger wind resistance power.

The weakness that these shuttlecocks brought is: during the ball arsis feel vibrations bigger, flying speed is fast.In order to improve this situation, people adopt the novel plastic elastomer to substitute original ball holder elastomeric material, have increased the peripheral tough and tensile soft characteristic of ball holder; Next is the radian that has changed ball bottom, has increased the contact-making surface of ball holder and racket when receiving, and has reduced the seismaesthesia of square stance hand; Be the external diameter that has suitably amplified the ball leaf once more, the skyborne flying speed of shuttlecock is slowed down.

Yet such improvement has produced side effect again, and in other words, the wind loading rating of shuttlecock descends, and is changed the direction of motion by wind easily.

The utility model content

Based on this, the utility model provides a kind of windproof shuttlecock, and this shuttlecock utilizes structural change, makes air resistance coefficient diminish, and is convenient to people and carries out badminton in various places.

The inventor finds after deliberation, movement velocity and the direction of shuttlecock in wind is that the weight that is subjected to shuttlecock, the other factorses such as air resistance coefficient of shuttlecock profile all directions influence, shuttlecock weight is a factor, be not The key factor, can not tackle the problem at its root so increase the weight of shuttlecock merely; Air resistance coefficient then is the key factor that influences shuttlecock flying speed and direction.

In the geometry of motion, arcuate structure or similar structure can reduce the influence power of wind effectively, opposite to recessed ball holder structure, or planar structure, bigger air resistance coefficient is brought in the capital, therefore present badminton structure can influence the speed of shuttlecock and change the direction of motion in flight course; Therefore, if reduce air resistance coefficient, be the key factor of a control shuttlecock flying speed and direction.

So the utility model provides a kind of like this implementation:

A kind of wind resistance shuttlecock, it comprises ball holder, ball leaf bar and ball leaf, ball bottom is an arcwall face, the anterior fixedly ball leaf bar of ball holder, ball leaf bar is outwards upheld, and its afterbody has the ball leaf, it is characterized in that ball holder front portion is provided with projection, projection protrudes in the residing plane of ball holder forward edge, and projection can be disperseed wind-force effectively like this, thereby reduces the influence of wind-force to shuttlecock flying speed and direction.

Described projection, it is arc-shaped curved surface, sphere, half water droplet face, taper, taper type structure any one.

Above-mentioned projection, it is preferably arc-shaped curved surface, sphere, half water droplet face constant current contour type structure any one.

Described projection, the height at its top, promptly the distance on top and ball holder forward edge plane of living in is that the 1/2-1/10 of ball holder diameter is best.

Described projection, the periphery of its underpart forms annular, and is attached at the surface of ball holder front portion.To form transition sleekly, reduce the effect of wind-force effectively.

Ball leaf and ball leaf are done present structure can increase the feather velocity of shuttle flight with the wind the time, the feather velocity of shuttle flight that then can slow down in the time of against the wind can change the direction of motion during crosswind.Air resistance coefficient is big more, and then the influence power of wind is big more, so described shuttlecock reduces ball leaf bar surface area or is designed to camber, can improve the wind resistance effect.

For the shuttlecock that non-feather is made, particularly for plastics/nylon/plastic cement system shuttlecock, the gap of its ball leaf increases, and can reduce the active force of wind-force to shuttlecock ball leaf, avoids shuttlecock offset direction at the volley.

And, especially for finding also in the research of plastics/nylon/plastic cement system shuttlecock that be used for the ball leaf bar that shuttlecock connects ball holder and ball leaf, its motion to shuttlecock also has considerable influence, therefore, reducing the resistance that ball leaf bar causes also is one of improved aspect of shuttlecock.

A kind of useful mode is ball leaf bar to be made as cross section be circular structure.

Another kind of useful mode is that ball leaf bar is made as cross section is oval-shaped structure.

For other mode, with ball leaf bar be made as the similar circle of cross section, oval-shaped form all is feasible.

In a word, the utility model adopts above-mentioned structure, and badminton structure is improved, and has reduced the air resistance coefficient of shuttlecock, and the resistance that wind-force is produced reduces, and does not move normally thereby do not influence shuttlecock, is convenient to people and launches a campaign in outdoor various places.

And the improvement of above-mentioned badminton structure, simple and practical, do not increase too much cost, also be convenient to make.
