[0003] Not ApplicableBACKGROUND OF THE INVENTION

[0004] The present invention relates generally to sound suppression devices. More particularly, the present invention relates to sound suppression for guns for use with projectiles other than bullets (e.g., shot shells, less than lethal projectiles, etc.).

[0005] Suppressors for guns, especially firearms are used to reduce noise levels and / or suppress or hide muzzle flash. Suppressors may be used on firearms or other guns such as air powered guns, especially pre-charged pneumatic guns. Suppressors use baffles and expansion chambers to reduce the noise emitted by a gun as the projectile exits the gun. Pistols and rifles shoot projectiles (i.e., bullets) that do not expand until impact with a target. That is, they maintain diameter when exiting a muzzle of the gun and passing through a suppressor affixed or integrated with the gun. Because the projectile maintains its diameter, baffles in the suppressor need only have a bore at least as large as the projectile and aligned with the path of travel of the projectile. The baffles only need to manage expanding gases, not any solid object impacts, and the baffles are therefore relatively thin and straight to minimize weight and material usage.

[0006] Suppressing guns that utilize expanding projectiles (e.g., shot shells, less lethal rounds, bean bags, pepper balls, etc.) is more challenging than typical ball ammunition or hollow point ammunition guns because the projectile diameter may increase as the projectile leaves the muzzle of the gun and travels through the suppressor. The suppressor must therefore limit projectile expansion within the suppressor to prevent the projectile from excessively impacting the baffles in the suppressor, destroying the projectile and the suppressor. At present, there are three ways to keep the projectile from expanding in the suppressor. The first way is to use baffles that are trumpet or bell shaped as shown in U.S. Pat. No. 11,774,205 to uniformly recompress an expanding projectile as it traverses the suppressor. Trumpet or bell shaped baffles are expensive to manufacture and can wear relatively quickly, but they allow good expansion of gases into the chambers in the suppressor created by the baffles. The second way is to use guide rods spaced about the circumference of the bore of the suppressor to keep the projectile diameter consistently constrained to its initial diameter as it traverses the suppressor. These rods allow good expansion of gases into the chambers between baffles, but the rods also allow expansion of areas of the projectile such that the expanded areas contact the baffles between the rods. The third way to limit projectile expansion within the suppressor is to use a perforated tube (which essentially forms a barrel extension) with baffles outside the tube. Perforated tubes are good at maintaining the dimeter of the projectile but tend to limit the expansion of gases into the chambers of the suppressor between the baffles because too holes or holes that are too large will result in a weak tube that is subject to failure.SUMMARY OF THE INVENTION

[0034] Referring now to FIGS. 1-10, a gun 101 includes a suppressor 100. The gun 101 includes a receiver 102 and a barrel 103. The receiver 102 is configured to initiate launching a projectile 105. The barrel 103 is configured to convey the projectile 105 forward from a rear end of the barrel at the receiver 102 to a muzzle of the barrel 103 at a forward end of the barrel 103.

[0035] The suppressor 100 includes a core 300, a baffle 501, a housing 503, and an end cap 505. The core 300 is configured to extend longitudinally. That is, the core 300 extends forward from the front end or muzzle of the barrel 103 along a longitudinal axis or bore axis of the barrel 103 when the gun 101 and suppressor 100 are assembled. The core has a rear end 301 configured to attach to the barrel 103 and a front end 303 opposite the rear end 301. In one embodiment, the core 300 is configured to attach to the barrel 103 via a barrel bushing 107. In one embodiment, the barrel bushing 107 is threaded onto the barrel 103, and the core 300 is threaded onto the barrel bushing. In another embodiment, the barrel bushing 107 is threaded into the barrel 103 and the core is threaded onto the barrel bushing 107. In another embodiment, a rear end of the core 300 is beveled complementary to a front end of the barrel bushing 107 such that when the core 300 is pressed against the complementary bevel in the barrel bushing 107 by the end cap 505 and housing 503, the core 300 is retained in position relative to the barrel bushing 107. In one embodiment, the barrel bushing 107 is threaded into a handguard surrounding the barrel to retain the barrel bushing 107 at the muzzle of the barrel 103.

[0036] The baffle 501 is configured to attach to an external surface 307 of the core 300 between the rear end 301 and the front end 303 of the core 300. The baffle(s) 501 extend radially outward to an inner surface of the housing 503, creating expansion chambers between the baffles 501, core 300, and housing 503. In one embodiment, the suppressor 100 includes a plurality of baffles 502, and the baffles 501 are configured to thread onto the core 300.

[0037] The housing 503 is configured to extend longitudinally about the core and the baffle(s) 501. The end cap 505 defines a front end of the suppressor 100 and is configured to attach to a front end of the housing 503. In one embodiment, the housing 503 threads onto the barrel bushing 503, and the end cap 505 threads into the housing 503. In one embodiment, the forward end 303 of the core contacts the end cap 505 to support the forward end 303 of the core 300. In one embodiment, the end cap 505 includes a plurality of teeth 313 extending forward of the housing 503. The teeth 313 can be used to engage a door hinge or latch to use the gun 101 as a breaching tool.

[0038] Referring especially to FIGS. 2-4, in one embodiment, the core 300 includes a plurality of annular segments 309 and rails 311. The plurality of annular segments 309 are spaced apart from one another and supported by the plurality of rails 311. The plurality of annular segments 309 are attached to and supported by the plurality of rails 311. In one embodiment, the plurality of rails 311 and the plurality of annular segments 309 are integrally formed. In one embodiment, a rear end of each of the annular segments 309 is beveled such that a rear edge 315 of the annular segment has a larger diameter than a minimum diameter of the annular segment, and the minimum diameter of the annular segment is approximately equal to a bore diameter of the barrel 103 of the gun 101. In one embodiment, an annular segment 309 includes threads forming the external surface 307 of the core 300. The baffle 501 is configured to engage the threads 307 such that the baffle 501 is retained radially and longitudinally relative to the annular segment 309. In one embodiment, the rails 311 are radially spaced from the longitudinal axis (i.e., the bore axis) the same distance as an outer diameter of the rear edge 315. That is, the projectile 105 should not normally expand to contact the rails 311 between annular segments 309, but the rails 311 will prevent any expansion beyond the maximum diameter of the annular segments 309 if an irregular operation occurs or a defective projectile 105 is launched.

[0039] Referring especially to FIGS. 5-7, in one embodiment, the core 300 includes annular segments 309 and rails 311 forming a cage (e.g., a monolithic core). The core 300 further includes a plurality of bushings 357. The plurality of bushings 357 engage a radially inward surface 359 of the cage. The plurality of bushings 357 are longitudinally spaced from one another when the suppressor 100 is assembled. In one embodiment, each bushing 357 of the plurality of bushings is beveled such that a rear edge 315 of the bushing 357 has a larger diameter than a minimum diameter of the bushing 357, and the minimum diameter of the bushing 357 is equal to or larger than the bore diameter of the barrel 103 of the gun 100. That is, the minimum diameter of the core 300 is approximately equal to the diameter of the barrel 103 and an outer diameter of the projectile 105.

[0040] Referring especially to FIGS. 8-10, in one embodiment, the core 300 includes a plurality of bushings 357 having a rear edge 315 that forms a hyperbolic paraboloid. Thus, instead of having annular spaces between the bushing 357, the spaces between the bushings have a shape that varies areas of the projectile 105 that could expand as the projectile passes between bushings 357 which will help to limit expansion of the projectile 105 and friction with the bushings 357 without hindering expansion of gases propelling the projectile 105 into the chambers between the baffles 501. In one embodiment, the rear edge 315 of the bushing 357 is generally flush with an inner surface of the rail 311 of the cage.

[0041] Referring especially to FIGS. 11-17, another embodiment of the suppressor 100 includes the core 300, the housing 503, and the baffle 501. The core is 300 is configured to extend longitudinally. In one embodiment, the core 300 is generally cylindrical. The core 300 has a rear end 301 configured to attach to the barrel 103 of the gun 101 and a front end 303 opposite the rear end 301. The core 300 extends along a longitudinal axis 709 (e.g., the bore axis of the barrel 103). The core 300 has an external surface 307 or wall 705 (i.e., sidewall). The wall 705 of the core 300 has a slot 707 therethrough. The slot 707 has a length longer than a width. The slot 707 may have rounded ends or square ends. The slot 707 is not parallel to the longitudinal axis 709 (i.e., a line along the length of the slot 707 is not parallel to the longitudinal axis 709), and the slot does not extend radially about the longitudinal axis 709 (i.e., a plane through the length of the slot 707 is not perpendicular to the longitudinal axis 709). In one embodiment, the slot 707 (e.g., a line along the length of the slot 707) spirals about the longitudinal axis 709 along the wall 705 of the core 300. In another embodiment, the slot 707 (e.g., a line along the length of the slot 707) is helical with respect to the longitudinal axis 709 along the wall 705 of the core 300. In one embodiment, the slot 707 (i.e., a line through the length of the slot 707) extends askew the longitudinal axis 709 (e.g. neither intersects nor is perpendicular or parallel). In one embodiment, the slot 707 has at least one support 733 extending across the slot 707 (see FIG. 17).

[0042] The housing 503 is configured to extend longitudinally about the core 300. In one embodiment, the housing 503 is configured to attach to the core by threading onto the core 300 at the front end 303 of the core 300. In one embodiment, the housing 503 has a reduced diameter at the one or more baffles 501. In one embodiment, the housing 503 includes a plurality of segments threadingly engaging one another. In one embodiment, a first portion 713 of baffle 501 extends radially inward from the housing 503 when the suppressor 100 is assembled.

[0043] The baffle 501 is configured to extend radially between the core 300 and the housing 503. In one embodiment, the baffle 501 is one of a plurality of baffles. Each baffle 501 extends radially between the core 300 and the housing 503 when the suppressor 100 is assembled. In one embodiment, the suppressor 100 includes a plurality of baffles 501 and a plurality of slots 707. The baffles 501 longitudinally separate one or a plurality of slots 707. That is, the baffles 501 are between the slots 707. In one embodiment, a second portion 715 of baffle 501 extends radially outward from the core 300 to the first portion 714 of the baffle 501 when the suppressor 100 is assembled.

[0044] In one embodiment, the suppressor 103 further comprises an end cap 505 at a front end 701 of the suppressor 100. In one embodiment, the end cap 505 defines the front end 701 of the suppressor 100. The end cap 505 is configured to attach to the front end 303 of the core 300 when the suppressor 100 is assembled by threading onto the core 300.

[0045] In one embodiment, the suppressor 100 further includes a barrel bushing 107. The barrel bushing 107 attaches to the barrel 103 of the gun 101 by threading onto / into the barrel 107 muzzle. The housing 503 attaches to the core 300 by threading onto the core 300 at the front end 303 of the core 300. In one embodiment, the end cap 505 acts as a jam nut securing the housing 503 in place on the core 300 (e.g. preventing rotation of the housing 503 relative to the core 300).
