Air or fire rifle with noise dampener
A rifle has a barrel defining a bore therein. A noise damper is provided adjacent a distal end of the barrel and defines a distal extension of the bore of the barrel. The noise damper includes a housing that is over-molded or over-injected on the barrel, such that the barrel, the noise damper and its housing define an integral assembly.
1. A rifle, comprising: a barrel defining a bore therein, the bore being configured and dimensioned for a projectile to be fired therethrough; a sound suppressor at a muzzle end of the barrel, the sound suppressor comprising sound suppressing elements, each of the sound suppressing elements defining an acoustic labyrinth therein, the sound suppressing elements being assembled to define a space therebetween, the space acting as an extension of the bore of the barrel; and a structure that is over-molded or over-injected upon the barrel and houses the sound suppressor, said structure: surrounding and in direct contact with the sound suppressor and a majority of the external surface of the barrel, defining an inner housing that houses the sound suppressor, and coupling the sound suppressor to the barrel such that the barrel, the sound suppressor, and the structure define an integral assembly.
2. The rifle of claim 1 , wherein each of the sound suppressing elements comprises partitions which at least partly define the acoustic labyrinth thereof.
3. The rifle of claim 2 , wherein each of the partitions defines a necking.
4. The rifle of claim 1 , further comprising a cover for closing an open end of the housing to retain the sound suppressor therein.
5. The rifle of claim 1 , further comprising a sight attached to the housing.
6. A rifle, comprising: a barrel defining a bore therein, the bore being configured and dimensioned for a projectile to be fired therethrough; a sound suppressor disposed at a muzzle end of the barrel; and a structure that is over-molded or over-injected upon the barrel, said structure: surrounding and in direct contact with the sound suppressor and a majority of the external surface of the barrel, defining an inner housing that houses the sound suppressor, and coupling the sound suppressor to the barrel such that the barrel, the sound suppressor, and the structure define an integral assembly.
7. The rifle of claim 6 , wherein the sound suppressor comprises a sound suppressing element within the housing adjacent the muzzle end of the barrel, and further wherein the sound suppressing element defines an acoustic labyrinth therein, and further defines a space therein, the space acting as an extension of the bore of the barrel.
8. The rifle of claim 7 , wherein the housing houses the majority of the barrel.
9. The rifle of claim 6 , wherein the sound suppressor is entirely encased within the housing adjacent the muzzle end of the barrel.
10. The rifle of claim 8 , wherein the sound suppressing element comprises partitions which at least partly define the acoustic labyrinth.
11. The rifle of claim 10 , wherein each of the partitions defines a necking.
12. The rifle of claim 6 , further comprising a cover for closing an open end of the housing to retain the sound suppressor therein.
13. The rifle of claim 6 , further comprising a sight attached to the structure.
14. A rifle, comprising: a barrel defining a bore therein, the bore being configured and dimensioned for a projectile to be fired therethrough; a sound suppressor disposed at a muzzle end of the barrel; and a structure that is over-molded or over-injected upon the barrel, said structure: surrounding and in direct contact with a majority of the external surface of the barrel, defining an inner housing that houses the sound suppressor, and coupling the sound suppressor to the barrel.
