Abstract

A variety of apparatuses and associated methods are provided for providing a retractable suppressor system for gas generator systems such as a firearm. One embodiment includes a suppressor system that includes a retractable structure and housing, a fixed baffle, floating baffles, and springs to displace the floating baffles within the suppressor as the suppressor is extended from the housing along a gas generator system, e.g. a barrel of a firearm and thereby enclose the barrel within the suppressor. Embodiments of the invention permit full retraction, partial retraction/extension, or full extension of an exemplary suppressor with respect to an emission section of the gas generator e.g., firearm muzzle. Embodiments of the invention include an external latch which enables an operator to latch or unlatch the suppressor as it moves from one position to another and prevents accidental activation. Embodiments of the invention are configured to operate with accessory mounting systems.

First claim

The invention claimed is:

1. A flash suppressor system comprising:
an accessory rail structure and a suppressor structure adapted to insert within said accessory rail structure;
wherein the accessory rail structure comprises
a plurality of parallel rail protrusions on an outer surface of the accessory rail structure configured to releasably engage with accessory equipment mounting structures;
a hollow body configured or formed to permit movement of said suppressor laterally along a first axis parallel with an outer wall of a barrel of a firearm within said hollow body, wherein the accessory rail structure is formed having a first aperture on a first rail structure end, a mounting structure on an opposing second rail structure end configured to mount or couple the accessory rail structure to a section of the firearm surrounding the barrel;
a guide movement channel or track defining a passage or channel set into or within a lateral section of an interior wall of said accessory rail structure along said first axis running parallel along said interior wall and the outer wall of the barrel;
a first and second removable and adjustable stop sections respectively disposed on opposing ends of a portion of said guide movement channel or track, the stop sections extending into said guide movement channel or track but not protruding past said interior wall surface;
a catch mounting and interface section formed into said accessory rail structure;
a spring loaded catch disposed within said catch mounting and interface section formed with a spring and a latch section that is configured to engage with a plurality of positioning slots into a side of the suppressor body in a retracted position, said spring loaded catch further including a lever protrusion that extends from an outer section of said accessory rail structure that is disposed in a gap between but not extending past two of the rail protrusions, wherein said spring loaded catch is configured to releasably engage with any one of said plurality of positioning slots so as to configure said suppressor to be fixed in a plurality of intermediate positions within extended and retracted positions;
wherein the suppressor comprises:
a suppressor body having an outer shape having a first suppressor body end formed with a second aperture formed to permit said barrel to move into and out of said second aperture that fits within the hollow body of said accessory rail structure;
a guide formed as a protrusion from the suppressor body configured to slideably engage within the guide movement channel or track between the forward stop and the rear stop which arrests movement of the guide in an extended and the retracted position;
a plurality of the positioning slots formed into the side of the suppressor body in a spaced apart pattern along said first axis;
a fixed barrel baffle that has a center aperture that is formed to receive and permit the barrel to pass into, the fixed barrel baffle is fixed to and extends away from a section of the outer wall of the barrel and is dimensioned to move with a clearance between an outer end of the fixed barrel baffle and an inner wall of the suppressor body;
a plurality of floating baffles configured with a floating baffle center aperture which slides over the outer wall of the barrel;
a first, second and third chamber spring sections each respectively disposed between the floating baffles, wherein said first, second and third chamber spring sections are formed and slideably disposed surrounding a section of the outer wall of the barrel, wherein the chamber springs sections are configured to apply pressure against lateral sides of the floating baffles so that when said spring loaded catch is moved and disengages with one of said plurality of positioning slots, said chamber spring sections move and extend the floating baffles within the suppressor along said barrel in a spaced apart manner and so are configured to route gasses from said gas generator from a muzzle section of said barrel through the floating baffles and thereby to selectively produce a suppressive effect of said gasses;
a bore restrictor moveably configured to slide over the second aperture when said barrel moves into said suppressor as it extends from said accessory rail structure through said first aperture, wherein said bore restrictor further is formed with a third aperture which is formed with a shape that permits a projectile fired out of said firearm to pass from said barrel through said bore restrictor when said bore restrictor is in the second position.

2. A system as in claim 1 , further comprising said firearm.

3. A system as in claim 1 , wherein the bore restrictor is fixed to the first suppressor body end in proximity to the second aperture by a pivot pin so that the bore restrictor slides away from the second aperture to permit the barrel to move into and out of the second aperture.

4. A system as in claim 3 , wherein said bore restrictor further includes a locking screw or structure which is configured to releasably couple said bore restrictor in a first and second position, wherein said first position configures said bore restrictor does not cover said second aperture and said second position covers said second aperture.

5. A system as in claim 4 , wherein the first suppressor body end is further formed with a receiving structure to receive said locking screw or structure when said bore restrictor is in the second position and thereby fix said bore restrictor in said second position.
