Description
[technical field]
The utility model relates to a kind of racket string, is meant a kind of being used on tennis or the racket especially, the racket string of tool hollow heart yearn.
[background technology]
Racket gut is of a great variety on the market, and its material is nothing more than nylon, staple fibre, sheep intestines or half catgut, catgut good springiness wherein, but easy to wear, be not durable; Nylon wire is attractive in appearance, but elasticity is poor slightly, is subjected to the influence of temperature also bigger, and meeting in winter embrittlement is easily broken.Above-mentioned two kinds of strings of a musical instrument not quite adopt in professional tennis or shuttlecock player, professional player's multiselect racket string of artificial fiber in the regulation game at present, because it has the strong point of catgut and nylon wire, avoided weakness separately, have simultaneously both solid and reliable, and rather good characteristics of elasticity, and artificial synthetic fiber it can comply with individual required again, utilize different braided wire methods, or different canoes, different-diameter and thickness made for selecting for use.
Owing to the striking surface of racket is to wear alternately to knit with one group of racket gut to be linked to frame, and form a preferable batting zone in face, be commonly called as " sweet district " (Sweet Spot), mainly be that spheroid is when being punched in sweet district, the elastic force of ball is bigger, and ball speed is very fast, does not more take arm strength, the player also is easier to utilize its playing skill to control ball, the size of selecting the sweet district that then determines its formation that weaves for use of racket gut, elasticity, with and extent of vibration.
Industry takes care of in sweet district area, elasticity and vibrational energy size or the like in the design of racket more for this reason, the big person of wherein sweet district area, and then the beginner is easier to left-hand seat, departs from the center a little and also can get to, and is difficult for fumbling; Elasticity preferably, then comparatively sharp in ball-handling, use arm strength less, handle fine and smooth split comparatively smoothly; Extent of vibration is hanged down the person, can reduce the player and impel contraction of muscle because of long-term vibration, and the athletic injury of the institute's arm muscle that causes load and fatigue is as " tennis elbow disease " etc.
The improvement of racket gut structure mainly is that sweet district area is strengthened at present, allows spheroid enter Tian Qu easily, increases elasticity to increase the handling of spheroid, reduces vibration and reduces because of vibratory impulse and cause arm load, and wear-resisting or the like function; Known racket string structure, it can be divided into single line heart yearn and multiple line heart yearn again, as No. 88208217 novel patent of TaiWan, China disclosed " structure-improved of racket string ", its first independent claims disclose the structure of a kind of centre for no heart yearn, consist predominantly of the winding silk of some predetermined lengths, it twines along an axis direction jointly in a spiral manner; One wire, it is a tool predetermined length and twining with this winding silk respectively.Its second independent claims are for having the structure of heart yearn in the middle of disclosing, consist predominantly of a central shaft, it has the monofilament of predetermined length or the filament of multifilament: one first winding layer, and it is that winding silk by some predetermined lengths is in a spiral manner outside this central shaft; One wire, in a spiral manner outside this central shaft, and it has and the different extension coefficient of this winding silk.
This structure mainly is to utilize respectively to have different extension coefficients between this winding filament and metal filament, after making with the spiral canoe, this racket string will have obvious convex-concave surface, make with racket with this racket string to have preferable ball-handling in square stance; But the elasticity of this racket string and the slow effect of shaking still can not satisfy actual needs, still remain to be improved.
[utility model content]

Should have at least one hollow-out parts by middle heart yearn, this hollow-out parts is located in this and is extended axially certain-length towards it on heart yearn and with hollow form.
The racket string of described tool hollow heart yearn; It is characterized in that: this first is in a spiral manner in this outside heart yearn around layer.
The racket string of described tool hollow heart yearn; It is characterized in that: it has more one second around layer, this second around layer be comprise the winding silk of many certain-lengths and in a spiral manner around this first around layer outer rim.
The racket string of described tool hollow heart yearn; It is characterized in that: it has more one second around layer, this second around layer be comprise the winding silk of many certain-lengths and in the interlacing mode around this first around layer outer rim.
The racket string of described tool hollow heart yearn; It is characterized in that: its most Wai Ceng Li is covered with a clad.
The racket string of described tool hollow heart yearn; It is characterized in that: this first is that mode with interlacing is in this outside heart yearn around layer.
The racket string of described tool hollow heart yearn; It is characterized in that: be equipped with at least two second hollow-out parts between this hollow-out parts and this middle heart yearn, this second hollow-out parts is located in this and is extended axially certain-length towards it on heart yearn and with hollow form.
The utility model also discloses a kind of racket string of tool hollow heart yearn, and it includes: many middle heart yearns are many line line bodies of tool certain-length; One clad is that the outer rim of being located at these many middle heart yearns also should coat by many middle heart yearns;
It is characterized in that: respectively should have a hollow-out parts respectively by middle heart yearn, this hollow-out parts is to be located in this to extend axially certain-length towards it on heart yearn and with hollow form.
The racket string of described tool hollow heart yearn; It is characterized in that: this hollow-out parts be with this in heart yearn be concentric circles.
The racket string of described tool hollow heart yearn; It is characterized in that: heart yearn and hollow-out parts are the triangles that is coaxial extension in respectively being somebody's turn to do.
The racket string of tool hollow heart yearn of the present utility model can be used on tennis or the racket, can promote its elastic force with increase ball-handling property, and can slow down vibration to reduce the athletic injury that hand causes.
