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.

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 ...

Embodiment Construction

[0037]Hereafter, the present invention will be explained based on the drawings. FIG. 1A shows a recoil reducer concerning an embodiment of the present invention. As shown in FIG. 1, a member 3 (hereafter, referred to as a forward moving member) is included in a casing 1 of a machine part so that the forward moving member 3 is slidably movable in an opposite direction with respect to a bolt 6. The forward moving member 3 has a substantially semicylindrical shape as shown in FIG. 1B and 1C. Movement restriction projections having a semicircular shape and projected downward are formed on both ends of the forward moving member 3. Thus, the forward moving member 3 has a U-shape as a whole when viewed from the side. The forward moving member 3 is installed on a slit groove (second slit groove) of the casing of the machine part by a protruding slit 32 so that the forward moving member 3 is slidably movable. The forward moving member 3 is in contact with a return spring 4 (second elastic bo...
