Device Capable of Generating Superposed Shock Wave

Abstract

A device capable of generating superposed shock waves, which is applied in a racket having a racket frame and having a racket string with warp strings and weft strings mutually woven to compose a string bed, and includes: at least one first main body formed as a hard medium, a lateral wall member is convexly formed at one side or two sides thereof, a first string slot having an opening at a top end is formed at an inner side of the lateral wall member or the center of the two lateral wall members, a recess is formed at the bottom end of the first string slot; and at least one soft medium, disposed in the first string slot and allowing the racket string to be fastened. As such, the shock wave can be returned for being backwardly transferred to increase the striking force for a ball member.

What is claimed is: 
     
         1 . A device capable of generating superposed shock waves, applied in a racket having a racket frame and having a racket string with a plurality of warp strings and a plurality of weft strings mutually woven to compose a string bed, and characterized in including:
 at least one first main body, formed as a hard medium, wherein a lateral wall member is convexly formed at one side or two sides thereof, a first string slot having an opening at a top end is formed at an inner side of the lateral wall member or the center of the two lateral wall members, a recess is formed at the bottom end of the first string slot, an arrangement of the lateral wall member and the two lateral wall members includes, but not limits to, a full segment or a middle segment of the first main body or a front segment and a rear segment in a staggering status or a rear segment and a front segment in a staggering status; and   at least one soft medium, disposed in the first string slot of the first main body and allowing the racket string to be fastened.   
     
     
         2 . The device capable of generating superposed shock waves as claimed in  claim 1 , wherein the bottom end of the first main body is disposed with a second main body which is a hard medium and arranged in an opposite direction, and a lateral wall member is convexly formed at one side or two sides thereof, a second string slot having an opening at a bottom end is formed at an inner side of the lateral wall member or the center of the two lateral wall members, a recess is formed at the bottom end of the second string slot, the second string slot is provided with the soft medium allowing the racket string to be fastened; an angle defined between the first main body and the second main body is able to be adjusted from 0 degree to positive or negative 180 degrees with respect to the racket string being staggered, an arrangement of the lateral wall member and the two lateral wall members includes, but not limits to, a full segment or a middle segment of the second main body or a front segment and a rear segment in a staggering status or a rear segment and a front segment in a staggering status. 
     
     
         3 . The device capable of generating superposed shock waves as claimed in  claim 2 , wherein the second main body arranged in the opposite direction and formed at the bottom end of the first main body is integrally formed. 
     
     
         4 . The device capable of generating superposed shock waves as claimed in  claim 1 , wherein the bottom end of the first main body is disposed with a first node plate having, but not limiting to, a round shape. 
     
     
         5 . The device capable of generating superposed shock waves as claimed in  claim 2 , wherein the bottom end of the first main body is disposed with a first node plate having, but not limiting to, a round shape. 
     
     
         6 . The device capable of generating superposed shock waves as claimed in  claim 5 , wherein the bottom end of the second main body is disposed with a second node plate having, but not limiting to, a round shape, and the second node plate and the first node plate are not integrally formed. 
     
     
         7 . The device capable of generating superposed shock waves as claimed in  claim 5 , wherein four corners of the first node plate of the first main body are formed with notches. 
     
     
         8 . The device capable of generating superposed shock waves as claimed in  claim 6 , four corners of the first node plate of the first main body are formed with notches, and four corners of the second node plate of the second main body are formed with notches. 
     
     
         9 . The device capable of generating superposed shock waves as claimed in  claim 6 , wherein at least one middle medium used for mutually fastening is provided between the first main body and the second main body or between the first node plate and the second node plate, the middle medium includes, but not limits to, the soft medium in a planar status or an adhesive, a fabric, a leather or particle glue for increasing the friction force and reaching a function of prohibiting shock waves generated through the warp strings and the weft warps which are top/down and horizontally/vertically arranged so as to be mutually isolated for avoiding mutual interferences. 
     
     
         10 . The device capable of generating superposed shock waves as claimed in  claim 6  or  8 , wherein an external soft medium connected to the soft medium is respectively disposed on the first node plate and the second node plate together with a lateral surface and a top surface of the first main body and the second main body; or the at least one external soft medium is disposed and used for covering the first node plate and the second node plate; or the at least one external soft medium is disposed and used for covering two sides of the first node plate and the second node plate. 
     
     
         11 . A device capable of generating superposed shock waves, applied in a racket having a racket frame and having a racket string with a plurality of warp strings and a plurality of weft strings mutually woven to compose a string bed, and characterized in including:
 at least one first main body, formed in a square shape or a rectangular shape and as a hard medium, wherein top ends defined at two sides thereof are respectively and convexly formed with a first string slot allowing the racket string to pass; and   at least one soft medium, formed in a circular status and disposed in the first string hole of the first main body and allowing the racket string to be fastened.   
     
     
         12 . The device capable of generating superposed shock waves as claimed in  claim 11 , wherein the bottom end of the first main body is disposed with at least one second main body which is a hard medium and arranged in an opposite direction and formed in a square shape or a rectangular shape, bottom ends defined at two sides of the second main body are respectively and convexly formed with a second string slot allowing the racket string to pass, the soft medium formed in a circular status and allowing the racket string to be fastened is disposed in the second string slot; and an angle defined between the first main body and the second main body is able to be adjusted from 0 degree to positive or negative 180 degrees with respect to the racket string being staggered.
