Bow mitigating initial torque

Abstract

A bow capable of mitigating a bad motion occurring in an initial stage of an arrow shootings includes a handle gripped by a user's hand; upper and lower limbs respectively coupled to upper and lower portions of the handle; a string having ends coupled to the upper and lower limbs; and a vibration damper coupled to the handle, the vibration damper being installed within a ±7 cm distance range in the up-down direction from a distance center point of the handle with the upper and lower limbs coupled thereto and positioned on a front surface of a grip portion of the handle.

1 . A bow, comprising:
 a handle gripped by a user's hand;   upper and lower limbs respectively coupled to upper and lower portions of the handle;   a string having ends coupled to the upper and lower limbs; and   a vibration damper coupled to the handle, wherein the vibration damper is positioned at a central portion of the handle with the upper and lower limbs coupled thereto and positioned on a front surface of a grip portion of the handle.   
   
   
       2 . The bow as claimed in  claim 1 , wherein the vibration damper is coupled within a ±7 cm distance range from a distance center point between the upper and lower limbs coupled to the handle in the up-down direction thereof. 
   
   
       3 . The bow as claimed in  claim 1 , wherein the vibration damper comprises:
 a fixing portion coupled and fixed to a body of the handle;   a vibration absorption portion mounted in the fixing portion to receive vibration occurring in the handle, transfer the vibration to the outside, and absorb and mitigate some of the vibration;   a coupling portion including the vibration absorption portion therein and coupled to the fixing portion; and   a weight coupled to the vibration absorption portion.   
   
   
       4 . A damper for a bow coupled to a handle of the bow, comprising:
 a fixing portion coupled and fixed to a body of the handle;   a vibration absorption portion mounted in the fixing portion to receive vibration occurring in the handle, transfer the vibration to the outside, and absorb and mitigate some of the vibration;   a coupling portion including the vibration absorption portion therein and coupled to the fixing portion; and   a weight coupled to the vibration absorption portion.   
   
   
       5 . The damper as claimed in  claim 4 , wherein the vibration absorption portion comprises a vibration transfer portion mounted in the fixing portion to receive vibration occurring in the handle and transfer the vibration to the outside; and an elastic portion for absorbing the vibration of the vibration transfer portion to mitigate the vibration. 
   
   
       6 . The damper as claimed in  claim 5 , wherein the elastic portion is made of an elastic body comprising at least one of a spring, rubber, urethane and silicone. 
   
   
       7 . The damper as claimed in  claim 5 , wherein the elastic portion comprises a horizontal elastic absorption portion for absorbing and mitigating front-rear vibration of the vibration transfer portion, and a peripheral elastic absorption portion for absorbing up-down-left-right vibration of the vibration transfer portion. 
   
   
       8 . The damper as claimed in  claim 7 , wherein the horizontal elastic absorption portion is formed in the shape of a spherical silicone ball, and the peripheral elastic absorption portion is formed of an elastic body comprising at least one of rubber, urethane and silicon and in the shape of a donut surrounding the vibration transfer portion.
