Abstract
The invention discloses a kind of radiused racket in the side of rounded square three, it is made up of frame, dabber and handle, it is characterized in that：The geometry of frame is developed on the basis of rounded square frame, and in addition to the side of this frame connected with dabber is constant, other three sides all carry out radiused differentiation：4mm 10mm are stretched out with the central point of straight line, straight line is developed into one section of circular arc line, the fillet of the two ends of circular arc line frame in smoothing junction again.At the top of the distance of centre of gravity racket head of frame apart from 112mm ± 5%, the frame center of gravity than known racket is significantly improved, because the distance at the top of the frame distance of centre of gravity racket head of known racket is 125 mm ± 5%.The beneficial effects of the invention are as follows the present invention is compared with known racket, and in the case where frame homogeneity is with weight, frame center of gravity is significantly improved, and cue power is also significantly increased therewith；Frame of the present invention can be competent at badminton line and draw high pound.
Description
Technical field
The present invention relates to a kind of racket, more particularly to a kind of radiused racket in the side of rounded square three.
Background technology
The frame of presently known racket has oval and lower oval two kinds of a capitiform in top, frame distance of centre of gravity racket head away from
From being all 125 mm ± 5%.The small people of dynamics is small using its strength of batting, and ball is beaten not far.Therefore, solution is producer constantly changing
The material of kind bat, though making moderate progress, improves little.In addition, the invention of number of patent application 2016109257462, Wu Huilin
Because frame center of gravity is significantly improved, according to lever principle, cue power also can substantially increase a kind of round rectangle racket therewith
Greatly；But, if round rectangle racket draws high a pound badminton line, 3 in four sides of round rectangle frame can be caused
Side produces obvious indent（This edge connected with dabber is because T robust construction will not produce indent）, so as to influence shuttlecock
The service life of bat.
The content of the invention
In order to overcome above-mentioned deficiency, the invention provides a kind of radiused racket in the side of rounded square three.
The technical scheme that is used to achieve the above object of the present invention is：
The radiused racket in the side of rounded square three, is made up of frame, dabber and handle, it is characterized in that：
The geometry of the frame be on the basis of rounded square frame develop, except connected with dabber this
The side of frame is constant outer, and other three sides all carry out radiused differentiation：4mm-10mm is stretched out with the central point of straight line, is made straight
Line develops into one section of circular arc line, the fillet of the two ends of circular arc line frame in smoothing junction again.The distance of centre of gravity racket head top of the frame
Apart from d=b+c=112mm ± 5%, the frame center of gravity than known racket significantly improves, because known racket
Distance at the top of frame distance of centre of gravity racket head is 125 mm ± 5%；The center of gravity of the frame is significantly improved, according to lever principle, batting
Dynamics can also be significantly increased therewith；Meanwhile, 3 sides of frame are because there is certain radian so that frame can be competent at shuttlecock
Line draws high pound.
The beneficial effects of the invention are as follows, the present invention compared with known racket, frame homogeneity with weight situation
Under, frame center of gravity is significantly improved, and cue power is also significantly increased therewith；Frame of the present invention can be competent at badminton line and draw high pound.
Brief description of the drawings
The present invention is further described with implementation below in conjunction with the accompanying drawings.Fig. 1 is schematic diagram of the invention, and Fig. 2 is three sides of frame
Carry out radiused differentiation schematic diagram.
In figure, 1 is frame, and 2 is dabber, and 3 is handle, and 4 is the side of frame, and 5 is the fillet of frame, and 6 is straight line, and 7 is round
Camber line, 8 is development.
Specific embodiment
In figure, the radiused racket in the side of rounded square three is made up of frame 1, dabber 2 and handle 3, it is characterized in that：
The geometry of the frame 1 be on the basis of rounded square frame develop, except connected with dabber 2 this
The side 4 of bar frame is constant outer, and other three sides all carry out radiused differentiation：C=5mm is stretched out with the central point of straight line 6, is made
Straight line 6 develops into one section of circular arc line 7, the fillet 5 of the two ends of circular arc line 7 frame in smoothing junction again.The radius a of the fillet 5 is
118mm；The length of the frame 1 is：2b+c=2*106+5=217 (mm), width is：2b+2c=2*106+2*5=222
(mm)；Distance at the top of the distance of centre of gravity racket head of the frame is d=b+c=106mm+5mm=111mm；The center of gravity of the frame is than public
The frame center of gravity of the racket known is significantly improved, because the distance at the top of the frame distance of centre of gravity racket head of known racket is
125 mm±5%；The center of gravity of the frame is significantly improved, and according to lever principle, cue power can also be significantly increased therewith；Meanwhile,
3 sides of frame are because there is certain radian so that frame can be competent at badminton line and draw high pound.
The above, is only presently preferred embodiments of the present invention, and any formal limitation is not made to the present invention, is appointed
What without departing from the present invention program content, any simple modification made to above example according to technical spirit of the invention, etc.
With change and modification, still fall within the range of technical solution of the present invention.
