Firearm Bolt Emulation Mechanism

Abstract

A firearm bolt emulation mechanism includes a bolt body. The bolt body includes a hand grip movably mounted thereon and having a function of reciprocal movement. The hand grip has an end coupled to a gas tube over which an elastic element is fit. The gas tube is coupled to a striker that is received in the bolt body. A knocker is received in the bolt body and is set on a reciprocal movement path of the striker. As such, for percussion, the hand grip is moved rearward to emulate a chambering operation and at the same time, the hand grip drives the gas tube and the gas tube drives the striker to move simultaneously. When the hand grip returns to the original position, the striker powerfully strikes the knocker so as to generate loud and clear sounding similar to the chambering sound of an actual firearm.

I claim: 
     
         1 . A firearm bolt emulation mechanism, comprising:
 a bolt body, which comprises a movably arranged hand grip, the hand grip having an end to which an elastic element is mounted for reciprocal movement of the hand grip;   a striker, which is received in the bolt body and coupled to the hand grip;   a knocker, which is received in the bolt body and is set on a moving path of the striker; and   an abutting member, which is fixedly mounted to one side of the striker to enhance tight engagement thereof with the knocker.   
     
     
         2 . The firearm bolt emulation mechanism according to  claim 1 , wherein the striker has a side forming a wavy section. 
     
     
         3 . The firearm bolt emulation mechanism according to  claim 2 , wherein the knocker has a side corresponding to the wavy section and forming a contact section. 
     
     
         4 . The firearm bolt emulation mechanism according to  claim 2 , wherein the abutting member is arranged to be distant from the wavy section. 
     
     
         5 . The firearm bolt emulation mechanism according to  claim 1 , wherein the knocker is arranged at location adjacent to a front end of a barrel of the bolt body. 
     
     
         6 . The firearm bolt emulation mechanism according to  claim 1 , wherein the elastic element is a spring. 
     
     
         7 . The firearm bolt emulation mechanism according to  claim 1 , wherein the striker and the knocker are solid metal pieces. 
     
     
         8 . The firearm bolt emulation mechanism according to  claim 1 , wherein the hand grip has an end opposite to the elastic element and fixedly coupled to a connection member, the connection member having an end fixedly coupled to the striker. 
     
     
         9 . A firearm bolt emulation mechanism, comprising:
 a bolt body, which comprises a movably arranged hand grip, the hand grip having an end to which an elastic element is mounted for reciprocal movement of the hand grip;   a striker, which is received in the bolt body and coupled to the hand grip;   a knocker, which is received in the bolt body and is set on a moving path of the striker; and   an abutting member, which is fixedly mounted to one side of the knocker to enhance tight engagement thereof with the striker.   
     
     
         10 . The firearm bolt emulation mechanism according to  claim 9 , wherein the striker has a side forming a wavy section and the knocker has a side corresponding to the wavy section and forming a contact section. 
     
     
         11 . The firearm bolt emulation mechanism according to  claim 10 , wherein the abutting member is arranged to be distant from the contact section. 
     
     
         12 . A firearm bolt emulation mechanism, comprising:
 a bolt body, which comprises a movably arranged hand grip, the hand grip having an end coupled to a gas tube, the gas tube comprising an elastic element to fit thereon;   a striker, which is received in the bolt body and is connected to an end of the gas tube; and   a knocker, which is received in the bolt body and is set on a moving path of the striker.   
     
     
         13 . The firearm bolt emulation mechanism according to  claim 12 , wherein the striker has one side forming a wavy section and the knocker has one side corresponding to the wavy section and forming a contact section.
