Offensive and defensive racket

Abstract

The invention provides an offensive and defensive racket which is characterized in that an elastic rod and a bowed string are arranged between a racket frame and a racket handle, wherein the elastic rod is arranged in the front; the bowed string is arranged in the back and looks like a bow; the elastic rod is equivalent to an elastic bow arm; and the bowed string is equivalent to a bow string with toughness. After the bow arm is tensioned by the bowed string, the bow arm cannot be bent out of the bow string but be bent toward the inside of the bow string only; and similarly, after the elasticrod is tensioned by the bowed string, the elastic rod cannot be bent toward the outer side surface of the bowed string, but be bent toward the inner side surface of the bowed string only. For the racket of such structure, the surface with the bowed string is used for hitting the ball, and the rigidity of the bowed string is good and suitable for offensiveness; and the surface with the elastic rodis used for returning the ball, and the rigidity of the elastic rod is good and suitable for defense. The offensive and defensive racket is a racket with different elasticity on the two surfaces, namely that one surface of the racket has good rigidity and is beneficial to offensiveness, and the other surface of the racket has good rigidity and is beneficial to defense.

Description

technical field [0001] The invention belongs to a sporting goods and relates to a racket, in particular to an offensive and defensive racket, which is mainly used for badminton rackets or tennis rackets. Background technique [0002] Chinese patent application number: 200710164335.7 Badminton racket with adjustable middle tube elastic point, a component built in the badminton handle that converts rotational force into axial movement force makes the badminton racket middle tube elastic point place a built-in part that can slide through the connecting rod The parts move axially in the middle tube, so as to adjust the position of the elastic point of the middle tube of the racket within a certain range, and change the force arm of the middle tube to achieve the best hitting effect, so as to be suitable for players with different qualities of explosive force, but the structure of this patent application more complicated.

[0002] Chinese patent application number: 200710164335.7 Badminton racket with adjustable middle tube elastic point, a component built in the badminton handle that converts rotational force into axial movement force makes the badminton racket middle tube elastic point place a built-in part that can slide through the connecting rod The parts move axially in the middle tube, so as to adjust the position of the elastic point of the middle tube of the racket within a certain range, and change the force arm of the middle tube to achieve the best hitting effect, so as to be suitable for players with different qualities of explosive force, but the structure of this patent application more complex

In addition, because the wall thickness gradually decreases from the rear end to the front end, it can flexibly control the hitting angle and help increase the hitting power, but the moment resistance of this patent application is poor

The above two patent applications are to change the characteristics of the racket from the middle tube of the racket. They are both good implementation methods, but not the best implementation method. Generally, the offensive type chooses a hard racket, and the defensive type soft racket
