This invention relates, generally, to firearm suppressors. More specifically, it relates to an adjustable sound, light, and heat shield configured to mount to a suppressor on a firearm and axially align with the firearm barrel.
Increased use of firearms has led to a desire to dampen the audible and visual effects associated with firearms. The suppression of sound, light, and heat from firearms is especially important in law enforcement and military operations. For example, it may be desirable for military personnel to remain hidden during an operation to prevent alerting an enemy combatant of their locations. Such military personnel often use firearm suppressors to remain hidden while discharging their weapons. Similarly, people often use suppressors when shooting targets on their property to prevent firearm noise from becoming a nuisance to neighbors. Hunters also use suppressors to prevent alerting animals of their presence.
Typically, firearm suppressors quiet the report of discharge to a safe level of less than 140 decibels. The resulting decibel level of suppressed gunfire is safer than unsuppressed gunfire, but can still be uncomfortably loud or even dangerous to a listener. This problem is especially present in interior combat situations, because the soundwaves created by gunfire ricochet against the walls, floor, and ceiling of an interior area, potentially causing hearing problems.
While gunfire reduced to 140 decibels is usually considered a safe degree of loudness, the suppressors may still fail to mask the presence of law enforcement or military personnel to a hostile party. The hostile party may become aware of an officer despite the use of a suppressor, placing the officers in great danger. Similarly, the noise generated despite the use of a suppressor can be bothersome to a hunter, as it can alert animals of the presence of the hunter.
The audible effects generated by a firearm during discharge include vibrational and acoustical soundwaves. When a firearm is discharged, vibrational and acoustical soundwaves travel through the barrel and escape from the firearm, leading to an audible noise. However, remnant effects of suppressed gunfire exist even with the use of a firearm suppressor. Suppressors fail to contain all of the vibrational soundwaves resulting from a firearm discharge. Instead, remnant vibrational soundwaves result from the contact between exploding blast gasses and the body of the suppressor. The vibrational soundwaves transfer through the body of the suppressor and radiate into the environment exterior to the suppressor. As such, the suppressor radiates vibrational soundwaves, which can alert a party of the presence of a firearm. Similarly, residual acoustical soundwaves escape the bore of the suppressor after a bullet is discharged through the suppressor bore. As the explosion of blast gas grows within the interior of the suppressor, the expanding gases are forced from the larger interior chamber of the suppressor, through the narrow aperture of the distal bore of the suppressor. When this occurs, the gases increase in velocity, and the corresponding acoustical soundwaves are amplified as they escape into the exterior environment.
Firearms also generate visual effects during discharge, including light and heat energy. The light and heat discharged by a firearm are partially dampened by a suppressor. The light energy results from the burning of propellant gas as a bullet leaves the barrel of the firearm. The hot gas reacts with the surrounding air at the muzzle of the gun, creating a flash of light referred to as the “muzzle blast” of the discharge. While suppressors capture some of the light from the reaction, some of the light energy escapes through the bore of the suppressor. The residual light is especially dangerous during low-light conditions, since the light contrasts with the darkness of the environment. Such light discharge can be deadly to law enforcement or military personnel if noticed by a hostile party.
Similarly, the burning of propellant gas generates heat energy that can exceed temperatures of 3,000° Fahrenheit. Suppressors are designed to absorb the heat generated from the high-temperature explosion resulting from gunfire, retaining the heat until the suppressor cools. However, residual heat can escape from the firearm during discharge, which can alert a party of the presence of a weapon. Equally dangerous is the heat signature of the suppressor upon absorption of heat after discharge. Since the suppressor is adapted to absorb and retain heat, the radiated heat can be detected by a hostile party, either through the naked eye or specialized electronic equipment. Again, the detection of the heat signature can be deadly to law enforcement or military personnel.
Accordingly, what is needed is a shield that can decrease the sound, light, and heat associated with the discharge of a firearm, despite the use of a suppressor. However, in view of the art considered as a whole at the time the present invention was made, it was not obvious to those of ordinary skill in the field of this invention how the shortcomings of the prior art could be overcome.

The long-standing but heretofore unfulfilled need for an adjustable sound, light, and heat shield configured to mount to a suppressor on a firearm and axially align with the firearm barrel is now met by a new, useful, and nonobvious invention.
The novel structure includes a residual effect shield used in combination with a firearm suppressor. The shield includes a proximal enclosure and a distal enclosure. The proximal enclosure has a proximal end, a distal end, and a body disposed therebetween. The proximal end includes an aperture sized to receive a portion of a firearm barrel.
The distal enclosure includes a distal end, a proximal end, and a body extending therebetween. The distal end includes a projectile aperture. A tapered structure is disposed within the body and longitudinally-spaced from the distal end to create a distal chamber. The tapered structure includes a proximal inner diameter that is greater than a distal inner diameter. As such, the tapered structure may be frustoconical in shape. The tapered structure is adapted to mate with the firearm suppressor, thereby aligning the firearm suppressor with the firearm barrel and the projectile aperture. In an embodiment, the tapered structure includes comprises a fluidic channel extending therethrough. The fluidic channel enables fluid in the distal chamber to pass through the tapered structure.
The proximal and distal enclosures are configured to attach to each other in an axially aligned configuration. Each of the proximal and distal enclosures include an inner diameter that is greater than an outer diameter of the firearm suppressor. At least some of the residual effects of a firearm discharge are dispersed throughout the proximal and distal enclosures.
In an embodiment, the proximal and distal enclosure include complementary threading. As such, the proximal and distal enclosures are adapted to threadedly mate via the complementary threading.
In one embodiment, the proximal and distal enclosures are housed within an enclosure. An interior surface of the enclosure and an exterior surface of both the proximal and distal enclosures include complementary threading. Accordingly, the enclosure threadedly engages with the proximal and distal enclosures via the complementary threading.
An interception device may be disposed adjacent to the projectile aperture. The interception device is tapered such that a distal diameter is greater than a proximal diameter. The interception device is adapted to direct the residual effects of the firearm discharge away from the projectile aperture and into the distal chamber.
An embodiment of a residual effect shield used in combination with a firearm suppressor includes an enclosure housing a compression sleeve, a spring, and an alignment partition. The enclosure includes a proximal end, a distal end, and a body disposed therebetween. The distal end includes a projectile aperture. The body may include a threaded portion.
The enclosure may include an interior receipt having an outer diameter that is smaller than an inner diameter of the enclosure. The different in diameters creates a translation channel between the enclosure and the interior receipt. The translation channel is in fluid communication with the chamber, thereby enabling fluid in the chamber to disperse into the translation channel.
The compression sleeve includes a proximal end, a distal end, and a body extending therebetween. The proximal end includes an aperture sized to receive a portion of a firearm barrel. The proximal end also includes at least one attachment arm adapted to translate in a radial direction to grip a proximal end of the firearm suppressor. Accordingly, the compression sleeve is adapted to exert a force against the firearm suppressor in an axial direction toward the distal end of the enclosure. The distal end of the compression sleeve is in communication with the body of the enclosure. In an embodiment, the distal end of the compression sleeve includes a threaded portion complementary to the threaded portion of the enclosure. As such, the compression sleeve is adapted to threadedly engage with the enclosure.
The spring is disposed at the distal end of the enclosure, the spring adapted to exert a force against the alignment partition in an axial direction toward the proximal end of the enclosure.
The alignment partition is disposed within the body of the enclosure and longitudinally-spaced from the distal end of the enclosure via the spring thereby creating a chamber. Accordingly, the alignment partition is adapted to contact a distal end of the firearm suppressor. At least some of the residual effects of a firearm discharge are dispersed throughout the chamber. The compression sleeve and the alignment partition are configured to align the firearm suppressor with the firearm barrel and the projectile aperture. The alignment partition may be adapted to axially translate along the translation channel formed by the interior receipt of the enclosure.
In an embodiment, the alignment partition includes a tapered structure. The tapered structure has a proximal inner diameter that is greater than a distal inner diameter. The tapered structure is configured to engage with the distal end of the firearm suppressor. The distal inner diameter is less than or equal to an outer diameter of the firearm suppressor. The tapered structure may be frustoconical in shape, such that the tapered structure is adapted to align the firearm suppressor with the firearm barrel and the projectile aperture.
In one embodiment, the alignment partition includes a fluidic channel extending therethrough, thereby enabling fluid in the chamber to pass through the alignment partition.
An embodiment of the present invention is a novel method for dampening residual effects of a firearm discharge from a firearm suppressor. The method includes enclosing a firearm suppressor within a shield, with the firearm suppressor attaching to a portion of a firearm barrel. The shield includes a proximal portion opposite a distal portion. The distal portion includes a tapered structure longitudinally-spaced from a projectile aperture. The tapered structure has a proximal inner diameter that is greater than a distal inner diameter.
The method includes a step of aligning the shield with the firearm suppressor by axially forcing the firearm barrel into the shield. As such, the firearm suppressor engages with the tapered structure, thereby causing the firearm suppressor to funnel into alignment with the shield. Upon discharge, at least some of the residual effects of a firearm discharge are dispersed throughout the shield.
It is an object of the invention to provide a device that further dampens the sound, light, and heat emitted from a firearm including a firearm suppressor. The shield of the present invention can be retrofit to a multitude of firearms and firearm suppressors having various geometries via adjustable dampening components. The shield includes one or more chambers to receive the residual effects of a firearm discharge from the firearm suppressor, thereby dampening the residual effects noticeable exterior to the firearm.
These and other important objects, advantages, and features of the invention will become clear as this disclosure proceeds.
The invention accordingly comprises the features of construction, combination of elements, and arrangement of parts that will be exemplified in the disclosure set forth hereinafter and the scope of the invention will be indicated in the claims.

In the following detailed description of the present invention, reference is made to the accompanying drawings, which form a part thereof, and within which are shown by way of illustration specific embodiments by which the invention may be practiced. It is to be understood that other embodiments may be utilized and structural changes may be made without departing from the scope of the invention.
The present invention includes a universal residual effect shield configured to mount to a firearm suppressor. While the firearm suppressor decreases the sound, light, and heat emitted by the firearm during discharge, residual effects may still be detectable outside of the firearm. The shield of the present invention includes at least one enclosure adapted to receive residual effects of a firearm discharge, thereby dampening the residual effects detectable outside of the firearm.

Proximal end 36a includes aperture 13. Aperture 13 is sized and shaped to receive at least a portion of barrel 11 therethrough. Accordingly, proximal end 36a is in communication with a firearm through barrel 11. Proximal end 36a also includes first tapered structure 14. First tapered structure 14 is intended to reside adjacent to suppressor 27 when suppressor 27 is secured within proximal enclosure 36.

Similar to distal end 36b of proximal enclosure 36, proximal end 18b of distal enclosure 18 includes suppressor receiving envelope 55. Suppressor 27 is inserted within suppressor receiving envelope 55, creating a seal between the structures. Suppressor receiving envelope 55 includes lateral circumferential wall 54, which may be lined with rubber or a similar material to aid in the frictional retention of suppressor 27.
Distal enclosure 18 includes second tapered structure 19 and chamber 61. Second tapered structure 19 is intended to reside adjacent to suppressor 27 when suppressor 27 is secured within distal enclosure 18. Second tapered structure 19 has a proximal inner diameter that is greater than a distal inner diameter, creating a taper on second tapered structure 19. As such, second tapered structure 19 may be frustoconical in shape. In addition, the proximal inner diameter of second tapered structure 19 is greater than the diameter of a muzzle end of the firearm suppressor and the distal inner diameter is less or equal to the diameter of the muzzle end of the firearm suppressor. The shape of second tapered structure 19 aligns suppressor 27 with barrel 11, as second tapered structure 19 forces suppressor 27 into an axial alignment due to the tapered sides. Second tapered structure 19 includes bore 58, as shown in
Second tapered structure 19 is longitudinally spaced from distal end 18a of distal enclosure 18, thereby creating chamber 61. Second tapered structure 19 is in fluid communication with chamber 61, such that some of the residual effects from discharge can translate between second tapered structure 19 and chamber 61. In particular, residual effects, such as gases, can disperse through second tapered structure 19 to chamber 61. To enhance the dispersion of residual effects into distal chamber 61, a plurality of fluid channels 33 are disposed on second tapered structure 19. Fluidic channels 33 provide fluid conduits through which gases and other residual effects can disperse. Some of the residual effects of the firearm discharge are dampened as the remaining sound, light, and heat energies are distributed throughout distal enclosure 18, in particular throughout chamber 61.

Similarly, distal enclosure 103 includes mounting surface 105 and tapered structure 164. Mounting surface 105 is adapted to engage with suppressor 127. Similar to mounting surface 104, mounting surface 105 is slidably adjustable in an axial direction with respect to suppressor 127. Tapered structure 164 is disposed adjacent to suppressor 127, and is frustoconical in shape, such that a distal end of tapered structure 164 has a greater diameter than a proximal end of tapered structure 164. The frustoconical shape of tapered structure 164 axially aligns suppressor 127 with a bore on tapered structure 164. Tapered structure 164 is longitudinally spaced from an end of housing 190. As shown in
As shown in
Projectile aperture 160 of housing 190 allows for the exit of a projectile from a firearm during discharge. Accordingly, projectile aperture 160 is axially aligned with a center axis of barrel 111, allowing for the uninterrupted travel of a projectile from barrel 111 and through projectile aperture 160. Because chamber 106 is disposed adjacent to projectile aperture 160, it is possible that some of the residual effects from firearm discharge would escape through projectile aperture 160 into the environment exterior to the firearm. To prevent the escape of these residual effects through projectile aperture 160, housing 109 includes interception device 113. Interception device 113 is disposed adjacent to projectile aperture 160. When a projectile exits projectile aperture 160, the residual gas and light from the discharge are directed toward interception device 113. Interception device 113 has a distal end and proximal end, and is frustoconical in shape. As such, the distal end has a greater outer diameter than a diameter of the proximal end. The shape of interception device 113 directs gas, heat, and light away from projectile aperture 160, thereby redirecting the residual effects throughout chamber 106. The residual effects noticeable exterior to the firearm are reduced as a result of interception device 113.
To assemble shield 100, both barrel 111 and a proximal end of suppressor 127 are inserted within aperture 102 of proximal enclosure 101. As such, extension 137 of barrel 111 mates with suppressor 127, with proximal enclosure surrounding a portion of suppressor 127. A distal end of suppressor 127 engages with tapered structure 164 on distal enclosure 103, with the frustoconical shape of tapered structure 164 axially aligning suppressor 127 with barrel 111. Proximal and distal enclosures 101, 103 are inserted within housing 190, with housing 190 threadedly engaging with proximal and distal enclosures 101, 103. As shown in

Attachment arm 201 axially extends in a direction away from the distal end of compression sleeve 202 and toward barrel 211. If more than one attachment arm 201 is included, the attachment arms 201 flare out and are disposed adjacent to suppressor 227. Attachment arm 201 is adapted to translate in a radial direction, such that attachment arm 201 is raised and lowered with respect to suppressor 227 when compression sleeve 202 surrounds suppressor 227. Attachment arm 201 translates within slots 220 in compression sleeve 202 when being radially translated. When lowered, attachment arm 201 rests against securement section 221 and attaches to a proximal end of suppressor 227. Accordingly, attachment arm 201 is adapted to grip suppressor 227, as shown in

Interior receipt 213 includes inner walls 210, end wall 212, and compression surface 230. Inner walls 210 are disposed at the proximal end of enclosure 208 and extend axially toward the distal end of enclosure 208. At the proximal end of enclosure 208, inner walls 210 include compression surface 230. Compression surface is adapted to mate with another structure and apply a compression force against the structure. End wall 212 is coupled to inner walls 210, forming interior receipt 213. Therefore, end wall 212 is disposed within the body of enclosure 208. Threading 207 is disposed on inner walls 210; the placement of threading 207 will be discussed in greater detail below.
Threading 207 is complementary to threading 203 of compression sleeve 202. As such, compression sleeve 202 threadedly engages with interior receipt 213. As compression sleeve 202 axially translates toward end wall 212, engaging with threading 207, compression sleeve 202 contacts compression surface 230. Compression surface 230 is adapted to radially translate attachment arms 201 toward suppressor 227, such that attachment arms 201 grip suppressor 227. As enclosure 208 is rotated with respect to compression sleeve 202, compression surface 230 forces attachment arms 201 to grip suppressor 227 and axially translate suppressor 227 toward projectile aperture 209.
As shown in
A portion of chamber 206 is disposed between projectile aperture 209 and end wall 212. Chamber 206 provides a space for the dispersion of residual effects resulting from firearm discharge. Chamber 206 will be discussed in greater detail below.

The interaction between spring 226 and alignment partition 205 creates chamber 206, which receives some of the residual effects of firearm discharge. The size of chamber 206 is determined by the compression of spring 226, which in turn is determined by the location of suppressor 227 within enclosure 208. The location of suppressor 227 is determined by the interaction between compression sleeve 202 and interior receipt 213. Specifically, the engagement between compression sleeve 202 and threading 207 causes suppressor 227 to axially translate away from barrel 211. The axial translation of suppressor 227 compresses spring 226. To ensure that spring 226 does not compress so much that chamber 206 is not created, threading 207 is disposed on a middle portion of interior receipt 213.

The method of dampening residual effects of firearm discharge begins at step 300, which includes enclosing firearm suppressor 227 within shield 200. Suppressor 227 is mated to a portion of barrel 211, such as extension 237. Shield 200 includes a proximal portion opposite a distal portion. The distal portion includes projectile aperture 209 and tapered structure 225. Tapered structure 225 is longitudinally-spaced from projectile aperture 209, such that tapered structure 225 is disposed between projectile aperture 209 and barrel 211. Tapered structure 225 has a proximal inner diameter that is greater than a distal inner diameter.
The method proceeds to step 310, which includes aligning shield 200 with suppressor 227. The alignment is step is accomplished by axially forcing barrel 211 into shield 200, such that suppressor 227 engages with tapered structure 225 disposed at the distal portion of shield 200. By forcing suppressor 227 to engage with tapered structure 225, suppressor 227 funnels into alignment with shield 200.
When shield 200 couples to suppressor 227, shield 200 substantially surrounds suppressor 227. Upon a firearm discharge, a portion of the effects of the discharge are captured by suppressor 227. However, suppressor 227 may not capture all of the effects from discharge, leaving residual effects that either escape the firearm, or are retained by another component. Shield 200 is adapted to capture at least some of the residual effects of the discharge. During step 320, some of the residual effects from discharge are dispersed throughout shield 200. As such, shield 200 dampens the residual effects noticeable in the environment exterior to the firearm.
