Abstract

The present invention provides a recoil reducer that reduces the recoil when the bullet is shot from the firearm and the bolt in the machine part is moved backward. By reducing the reaction force applied to the bolt when the bullet is shot, a load applied to the shooter is reduced. Furthermore, hit accuracy is improved by stabilizing the sight, the performance of the firearm itself is not decreased. The recoil when the bullet is shot is reduced by providing a member moving in an opposite direction of a recoil direction of a bolt and providing a transmission mechanism that moves the member in the opposite direction of the recoil direction of the bolt when the bolt is moved in the recoil direction by a reaction force of shooting a bullet.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A recoil reducer, comprising:
 a bolt that is installed on a first slit groove of a casing of a machine part and is slidably movable with respect to the casing;   a forward moving member that is installed on a second slit groove of the casing of the machine part and is slidably movable with respect to the casing in an opposite direction of a recoil direction of the bolt;   a transmission mechanism that moves the forward moving member in the opposite direction of the recoil direction of the bolt when the bolt is moved in the recoil direction by a reaction force of shooting a bullet;   a first elastic body that is located between an end portion of the bolt in the recoil direction and the machine part; and   a second elastic body that is located between an end portion of the forward moving member in a forward direction and the machine part.   
     
     
         2 . The recoil reducer according to  claim 1 , wherein
 a rotating body, which is slid or engaged between the bolt and the forward moving member, is used as the transmission mechanism.   
     
     
         3 . The recoil reducer according to  claim 2 , wherein
 a rack and pinion gear and a gear are used in a part of the rotating body as the transmission mechanism.   
     
     
         4 . The recoil reducer according to  claim 1 , wherein
 a combination of a chain and a sprocket, or a combination of a belt and a pulley is used as the transmission mechanism.
