Recoil reducer when shooting bullet from firearm

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.

Description

CROSS-REFERENCES TO RELATED APPLICATIONS[0001]This patent specification is based on Japanese patent application, No. 2014-132957 filed on Jun. 27, 2014 in the Japan Patent Office, the entire contents of which are incorporated by reference herein.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention:[0003]The present invention relates to a device that weakens the impact of recoil to stabilize the sight and reduce a load applied to hands and shoulders of a shooter when a bullet is shot from a firearm (e.g., rifle) and a bolt, a barrel and the like are moved in a recoil direction.[0004]2. Description of the Related Art:[0005]FIG. 7A shows an outer appearance of a typical rifle for hunting or sport shooting. In a general firearm, a bolt housed in a casing of a machine part, from which a bullet is shot, is moved in the recoil direction by a reaction force when gunpowder is ignited to shoot the bullet, the recoil when shooting the bullet is received by a recoil spring provided on an ...

AI Technical Summary

Benefits of technology

[0016]By using the present invention, the reaction force applied to the bolt when shooting the bullet is also directed to the forward direction (shooting direction of the bullet) by the transmission mechanism. Thus, the reaction force applied to the bolt when shooting the bullet is reduced by the repulsion force of the elastic body (e.g. return spring, rubber and resin) which is in contact with the forward moving member and sliding resistance of the rotating body. Consequently, by using the recoil reducer of the present invention, the load applied to the shooter is reduced, the barrel is prevented from moving upwardly, and no problem occurs when the bolt is returned to the original position in the machine part after shooting the bullet.

Problems solved by technology

Therefore, the impact when the bullet is shot is very large.

For the shooter, it is a heavy burden to bear the impact and the sight is misaligned as a result.

However, as a disadvantage, too much time is required for the bolt 6 to return to the original position after the bullet is shot.

In addition, explosion property of the propellant of the bullet is limited.

However, the movement of the return becomes slow and therefore bad influence may occur when loading the next bullet, for example.

However, since the barrel itself is moved forward as a counterweight, shooting force itself is decreased and therefore bad influence may occur in the performance of the gun.
