A kind of extending two-sided tennis racket shortened

Technical field

This utility model relates to a kind of tennis racket, is specifically related to a kind of two-sided tennis racket changing length, belongs to sports goods technical field.

Background technology

Tennis is the sports of a grace and fierceness, and the origin and the development of tennis can be summarized by four words: breeds in France, is born in Britain, starts universal and forms climax in the U.S., and the present whole world prevailing is referred to as second-biggest-in-the-world ball game.Generally carry out between two singles sportsmen or two pairs of doubles combinations.Sportsman impacts tennis across net tennis racket on tennis court, and the Birmingham, GBR in 19th century is born in modern tennis.In 20th century, tennis obtains broad development all over the world, and becomes global sports.Tennis tournament of greatest concern is four the tennis four grand slam races held every year.

The most original form of tennis is referred to as court tennis (Realtennis).Most of historians think, this motion originates from a kind of game that 12 th Century French the north missionaries bat the ball in the claustra of church the earliest.To 14 middle of century, a poet of France makes referrals to this ball game in France imperial palace, as the pastime of royal noble men and women.Playing this game at that time, place is the hall in imperial palace, it does not have net, also without racket, is tied up into rope after ball yardage roll is circular.Erecting a rope in the middle of place is boundary, utilizes two handss to make racket, and ball is lost from rope, and French is called.To 16th century, the racket of plank is used to replace two handss to bounce the ball.Initial tennis, simply two hemisphere fill what grass, leaves or hair etc. were made, and later along with the development of tennis, the making of ball is also more and more exquisite.

16 beginnings of the century, this ball game, by the national discovery of France, starts out of curiosity to imitate, propagates each big city soon, improve apparatus simultaneously.Ball is made to relatively durable, and bat is changed into Corii Caprae seu Ovis cardboard by plank, and face area amplifies, and the handle of handle also lengthens.Rope in the middle of place, increases countless short rope and hangs down earthward, ball from rope pass below time, it is possible to realize significantly.Ordered to forbid by the French King Louis later, and specified that this was the privilege game in imperial palace.

At the beginning of the 17th century, no longer with rope curtain in the middle of place, and using lattice net instead, net is better than the effect of curtain, and bat is used the net of threading instead and clapped, high resilience and also lightly facilitate.France imperial palace in make this game time, side, court place a golden container, every time no side after, money is put in dish by spectators, as the prize of victor.This method purpose originally is fine, and gradually developing later becomes a kind of gambling.During beginning, number is still little, gambles bigger and bigger in the course of time, even has people therefore to go bankrupt or broke, and then dispute is happened frequently, and the French King orders to forbid to remake this kind of game then, here it is 18th century main cause that decays of initial stage tennis.

Tennis racket is made up of racket head, bat larynx, handle, also needs in use coordinate the accessories such as tennis line, shock absorber to use, the tennis racket brand that current international market share is the highest.Famous product line is: hammer (hammer series), prostaff (star's series), ROLLERS (prestige wheel series), TRIAD series.So, how selecting oneself tennis racket suitable also to make an important thing, therefore we should be noted that, the weight of racket is to select the first element of tennis racket, because racket too heavily can make the slow movement that sportsman swings the bat, but can provide bigger striking force.And although lighter racket is waved when beating light flexibly, but for then easily reproduction the other side's heavy ball；The handle size of tennis racket is also the key factor selecting tennis racket, though the too thick feel of handle is good but is not easy to process bead, and handle too detailed rules and regulations should not be firmly grasped, the chance easy reproduction of heavy ball.Standard network racket handle size is between right 5/8 inch of 4 right sides 1/8 to 4.1 to No. 5 corresponding European handles, what most domestic people selected is 1, No. 2 handles, and schoolgirl is generally selected No. 1 handle.The size of handle with after holding bat, thumb and middle finger forefinger see have a span from；The face of tennis racket has little face: 85-90 square inch, middle face: 92-102 square inch, big face: 104-115 square inch, super large face: these are several for 116-135 square inch, bigger face can provide bigger hitting region and dessert, it is easier to impact, but lack speed, be relatively suitable for schoolgirl.For asking most ball speed and the sportsman controlled then to may select little face etc..

Tennis is the motion that we like; Just because of this; the requirement of tennis racket is also improved by we constantly; existing tennis racket can meet the basic demand of people, it is possible to impact tennis, and material is also fine; can life-time service; but the design of these tennis rackets is too simple, it is impossible to meet the demand of special population, also having is exactly that existing racket does not account for how people improve the enjoyment during people play ball and the protection etc. to people.
