Abstract

An elastic rod and a tension string are arranged between a frame and a handle of an offensive and defensive racket. The elastic rod is at the front, the tension string is at the rear, the elastic rod and the tension string are formed into a bow, the elastic rod is equivalent to an elastic bow arm, and the tension string is equivalent to a flexible bowstring. After being tensioned by the bowstring, the bow arm cannot be curved away from the bowstring any more, but only can be curved toward the bowstring, and likewise, after being tensioned by the tension string, the elastic rod cannot be curved away from the tension string any more, but only can be curved toward the tension string. The side of the racket with the structure, which has the tension spring, is used for hitting a shuttlecock, and the rigidity is just suitable for offense; the side with the elastic rod is used for returning the shuttlecock, and the elasticity is just suitable for defense. The offensive and defensive racket has the advantages that: the offensive and defensive racket is a racket, of which both sides have different degrees of elasticity, i.e., one side of the racket has high rigidity which is favorable for offense, and the other side has high elasticity which is favorable for defense.

Description

Attacking and defending type racket

Technical field

The utility model belongs to a kind of sports goods, relates to racket, and especially a kind of attacking and defending type racket is mainly used in racket or tennis racket.

Background technology

Chinese patent application number: tubular elastic point adjustable type racket in 200710164335.7, make by connecting rod by the built-in parts that revolving force is converted into axial moving force of badminton racket handle that the built-in slidable member in tubular elastic point place axially moves in the racket in middle pipe, thereby reach regulate within the specific limits in the racket tubular elastic point position change in the pipe arm of force and reach the best and hit effect, being applicable to the player of different quality explosive force, but the structure of this patent application is complicated.Chinese patent application number: the 200910053848.X racket, it comprises middle pipe, be connected in the pipe front end a frame and be connected in the handle of pipe rear end.Pipe is the tubulose of external diameter unanimity in being somebody's turn to do, and wall thickness reduces gradually from the rear end forward end.The utility model moves on the inflection point by the feasible middle pipe of wall thickness of pipe in changing, thereby has increased the force arm when swinging the bat, and can increase the batting dynamics thus.In addition, because wall thickness reduces from the rear end to the front end gradually, thereby can control angle of shot flexibly and help again to increase the batting dynamics, but the resisting moment of this patent application is relatively poor.Above two patent applications all be the characteristic that pipe changes racket from racket, all be good implementation method, but be not best implementation method that ordinary circumstance is the attack-oriented partially hard racket of bar of choosing, partially defensively oriented is chosen the soft racket of bar.

Summary of the invention

In order further to improve racket series, the utility model tries hard to provide a kind of attacking and defending type racket.Main purpose is to help attack for the one side that makes racket has good rigidity, and another side has good elasticity and helps defence.

The technical scheme that its technical problem that solves the utility model adopts is: flexible bar and draw string between frame and the handle.Elastic rod draws string in the back in front, similarly is one to draw a bow, and elastic rod is equivalent to flexible bow arm, draws string to be equivalent to the bowstring of flexible.Because bowstring can only bear pulling force, can not bear pressure, or else the bow arm is subjected to after the bowstring tension can be to the bowstring outside sweep, can only be crooked in bowstring, in like manner, and or else can be after the tension of elastic rod tension string to the lateral surface bending of drawing string, can only be to the medial surface bending of drawing string.The racket of this structure, with the one side batting of drawing string, good rigidly is suitable for attack; With the one side return of serve of elastic rod, good springiness is suitable for defence.Elastic rod can use spring steel, high resiliency carbon materials or composite elastomeric material to make, and draws string can use steel wire, steel band, various rope to make.

The beneficial effects of the utility model are, attacking and defending type racket is that a kind of two sides has different flexible rackets, and promptly the one side of racket has good rigidity and helps attack, and another side has good elasticity and helps defence.

The specific embodiment

Fig. 1 is the schematic diagram of the utility model attacking and defending type racket.Among the figure, flexible bar (2) and draw string (4) between frame (1) and the handle (3), elastic rod (2) is to be made into bow-shaped structural with a strip material, drawing string (4) is a thin steel band.Elastic rod (2) draws string (4) in the back in front, similarly is one to draw a bow, and elastic rod (2) is equivalent to flexible bow arm, draws string (4) to be equivalent to the bowstring of flexible.Or else the bow arm is subjected to after the bowstring tension can be to the bowstring outside sweep, can only be crooked in bowstring, in like manner, and or else can be after elastic rod (2) tension string (4) tension to drawing string (4) lateral surface bending, can only be to the medial surface bending of drawing string (4).The racket of this structure, with the one side batting of drawing string (4), good rigidly is suitable for attack; With the one side return of serve of elastic rod (2), good springiness is suitable for defence.The material of elastic rod (2) preferably can be gone up narrow, widens gradually downwards again, and making it from top to bottom, rigidity becomes big gradually.

Claims

1. attacking and defending type racket is characterized in that: flexible bar and draw string between frame and the handle, elastic rod draws string in the back in front.
