Abstract
A heat dissipation promoting ventilated protective guard for a firearm suppressor also known as a moderator can include a substantially cylindrical cage shaped body surrounding an inner void that can contain the suppressor. In inwardly projecting beveled stop-surface on the guard bears against a corresponding beveled shoulder on the suppressor to limit axial movement. A snap-ring and wave spring bias the guard against the shoulder. Slits and vents in the mounted guard allow air to pass over the suppressor and prevent contact by a user with a dangerously hot suppressor.
Claims13
The combination of a ventilating heat guard coaxially mounted to a firearm suppressor;
- wherein said suppressor comprises:
- an oblong outer shell having a central axial bore allowing the passage of a projectile therethrough from a proximal end to a distal end;
- a radially outwardly projecting peripheral beveled shoulder;
- wherein said heat guard comprises:
- a body having an inner void shaped and dimensioned to accommodate said suppressor;
- said body having a proximal opening to said void and a distal opening to said void;
- a radially inwardly projecting beveled stop surface;
- wherein said beveled stop surface bears against said beveled shoulder, preventing axial movement of said guard with respect to said suppressor in a first axial direction;
- wherein said combination further comprises:
- said guard further comprising a plurality of angularly spaced apart inwardly extending radial lugs located near a proximal end of said guard;
- said suppressor further comprising a plurality of notches engaged by said lugs;
- thereby preventing angular movement of said guard with respect to said suppressor.
The combination of a ventilating heat guard coaxially mounted to a firearm suppressor;
- wherein said suppressor comprises:
- an oblong outer shell having a central axial bore allowing the passage of a projectile therethrough from a proximal end to a distal end;
- a radially outwardly projecting peripheral beveled shoulder;
- wherein said heat guard comprises:
- a body having an inner void shaped and dimensioned to accommodate said suppressor;
- said body having a proximal opening to said void and a distal opening to said void;
- a radially inwardly projecting beveled stop surface;
- wherein said beveled stop surface bears against said beveled shoulder, preventing axial movement of said guard with respect to said suppressor in a first axial direction;
- wherein said combination further comprises:
- a disk-shaped axial bearing surface located near said proximal opening;
- and wherein said suppressor further comprises:
- a circumferential groove near said proximal end;
- a snap-ring resting within said groove;
- a wave spring compressed between said snap-ring and said axial bearing surface.
The combination of a ventilating heat guard coaxially mounted to a firearm suppressor;
- wherein said suppressor comprises:
- an oblong outer shell having a central axial bore allowing the passage of a projectile therethrough from a proximal end to a distal end;
- a radially outwardly projecting peripheral beveled shoulder;
- wherein said heat guard comprises:
- a body having an inner void shaped and dimensioned to accommodate said suppressor;
- said body having a proximal opening to said void and a distal opening to said void;
- a radially inwardly projecting beveled stop surface;
- wherein said beveled stop surface bears against said beveled shoulder, preventing axial movement of said guard with respect to said suppressor in a first axial direction;
- wherein said combination further comprises:
- said guard further comprising a plurality of axially oblong angularly spaced apart slits extending radially through said body from an outer surface to said void;
- wherein said slits are located distal to said beveled stop-surface.
A method for protecting a user from burns by a firearm suppressor, said method comprises:
- selecting a suppressor having an outer shell having a beveled shoulder;
- selecting a guard having an inner void that can accommodate said suppressor, and having complimentary beveled stop-surface extending into said void;
- aligning said guard angularly with said suppressor so that angular alignment structures line up;
- inserting coaxially a proximal end of said suppressor into a distal opening of said guard until said beveled shoulder contacts said beveled stop-surface;
- locking the axial position of said suppressor with respect to said guard;
- firing said firearm until said suppressor becomes dangerously hot;
- touching the guard without being burned;
- and,
- applying torque to said guard to remove said guard from said suppressor while said suppressor is dangerously hot.
