Definitions
- This patent generally pertains to firearms and more specifically to devices and methods for inhibiting the firearm's unauthorized use or accidental discharge.
- a firearm also known as a gun
- a firearm is an apparatus comprising a barrel, an action mechanism, and a firing chamber from which one or more projectiles are propelled by an explosive.
- the firing chamber at a breech end of the barrel is where a live cartridge is situated just prior to firing.
- the terms, “firing” and “discharging” are used interchangeably.
- a cartridge comprises a cartridge case containing the explosive and holds the bullet or projectile(s). When fired, the explosive propels the bullet out through a muzzle end of the barrel.
- the action mechanism provides one or more functions. Examples of such functions include firing the gun, ejecting the spent cartridge case after firing, and/or reloading the next live cartridge into the firing chamber.
- long gun refers to any firearm with a barrel length of at least sixteen inches. Some long guns include a stock for bracing the firearm against a shooter's shoulder.
- handgun refers to any firearm with a barrel length of less than sixteen inches.
- rifle refers to a long gun having a barrel with a helically grooved bore, known as rifling. Rifles typically fire a projectile or bullet that prior to firing is attached to and projects forward from a cartridge case. Many long guns utilize a variety of types of action mechanisms (e.g., bolt action, lever action, pump action, etc.).
- shotgun refers to a long gun having a barrel with usually a smooth bore. Shot guns typically fire one or more projectiles that prior to firing are enclosed within a cartridge case.
- Pistol refers to a handgun with a single firing chamber. Pistols typically include a striker-fired firing pin or a hammer-fired firing pin.
- the firing chamber is usually integral to the barrel.
- the action mechanism includes a slide that moves a live cartridge into the firing chamber and ensures the action mechanism is in battery position, then fires it (e.g., via a hammer or striker-fired pin), and then ejects the case from the firing chamber.
- the battery position is when the cartridge is ready to be fired and a breech cover is in position to fire the live cartridge.
- bullets are discharged sequentially from the same firing chamber.
- revolver refers to a handgun with a revolving cylinder containing a series of chambers.
- the aligned chamber becomes the firing chamber.
- the firing chamber is separate from the barrel, but at the breech end and is in alignment with the barrel.
- the action mechanism of a revolver is the cylinder with its associated mechanism that rotates the next chamber into battery position, fires it, and then rotates that chamber out of battery position while bringing in the next chamber to battery position. Initially, each firing chamber is loaded with a live cartridge. After firing a live cartridge, the revolver's action mechanism rotates the cylinder to move the chamber with the spent cartridge away from the breech end of the barrel and move the next chamber with a live cartridge in its place to be fired at the next shot.
- Such devices are available for inhibiting unauthorized use of a firearm and for preventing it from being accidentally discharged. Such devices typically disable one or more functional elements of a firearm. Examples of such functional elements include the firearm's trigger, barrel and hammer.

- firearm refers to any apparatus comprising a barrel, an action mechanism, and a firing chamber from which one or more projectiles (e.g., a bullet, shot, etc.) are propelled by an explosive.
- Some examples of firearm 15 include a pistol 12 (e.g., a hammer or a striker fired), a revolver 96 , and a long gun 104 (e.g., a rifle or a shotgun).
- Each gun-locking device 10 includes a rod extending through a barrel of the firearm 15 and into the firing chamber to ensure there is no bullet or live cartridge in the chamber.
- the gun-locking device 10 a is attachable to the pistol 12 with a barrel 14 that is less than 16 inches long.
- the pistol 12 comprises a frame 16 , a grip 18 , the barrel 14 , a front sight 20 at a muzzle end 22 , a rear sight 24 at a breech end 26 , a hammer 28 at the breech end 26 , a trigger 30 , a trigger guard 32 , a firing chamber 34 defined by at least one of the frame 16 and the barrel 14 , and an action mechanism 36 (e.g., a slide action).
- an action mechanism 36 e.g., a slide action
- the action mechanism 36 is movably attached to the frame 16 to (a) enable firing of the pistol 12 , (b) eject a spent cartridge case 38 after firing, and (c) reload a next live cartridge 46 into the firing chamber 34 .
- the pistol 12 includes a firing pin 42 for delivering the hammer's impact to a primer of a live cartridge 40 when loaded in the firing chamber 34 .
- a striker-fired firing pin (without the hammer 28 ) is what delivers an impact to the primer.
- pistol 10 a include a magazine 44 for feeding live cartridges 40 individually to the firing chamber 34 .
- each cartridge 40 comprises a bullet 46 attached to the front end of a cartridge case 48 .
- FIG. 4 happens to show an empty spent cartridge case 38 in firing chamber 34 .
- the firing chamber 34 at times is completely empty.
- the firing chamber 34 contains a live cartridge 40 with the bullet 46 still attached to the cartridge case 48 .
- gun-locking device 10 a comprises a muzzle retainer 50 and a breech retainer 52 .
- the muzzle retainer 50 comprises a front member 54 and a front arm 56 .
- the front arm 56 has a front distal end 58 extending rearward from the front member 54 .
- Some examples of gun-locking device 10 a include a rod 60 with a proximal end 62 and a distal end 64 , wherein the proximal end 62 is adjacent and attached to the front member 54 of the muzzle retainer 50 .
- the rod's distal end 64 extends rearward away from the front member 50 .
- the breech retainer 52 comprises a rear member 66 and a rear arm 68 .
- the rear arm 68 has a distal end 70 extending forward from the rear member 66 .
- gun-locking device 10 a is configurable selectively to a locked configuration ( FIGS. 1, 2, and 4 ) and a released configuration ( FIG. 3 ).
- the locked configuration the front member 54 and the rear member 66 are slid together to capture the pistol 12 between the gun-locking device's front member 54 and rear member 66 .
- the front member 54 engages the pistol's muzzle end 22
- the rear member 66 engages the pistol's breech end 26
- the front arm 56 overlaps both the rear arm 68 and the barrel 14 .
- the front arm 56 and the rear arm 68 overlap directly above the pistol's action mechanism 36 to hold them onto the pistol and thus prevent the action mechanism 36 from operating.
- overlap refers to one part at least partially covering the other part as viewed from a direction perpendicular to a longitudinal axis 162 of the firearm's barrel 14 .
- the front member 54 of the muzzle retainer 50 is closer to the rear member's rear distal end 70 than to the front member's front distal end 58 .
- the breech retainer's rear member 52 is closer to the front member's front distal end 58 than to the rear member's rear distal end 70 .
- the rod 60 extends through the barrel 14 and at least partially into the firing chamber 34 to ensure that the firing chamber 34 is empty or at least void of a live cartridge 40 with an attached bullet 46 .
- the rod's proximal end 62 has an outer diameter 72 that is larger than an outer diameter 74 of the rod's distal end 64 .
- the rod's proximal end 62 has an axial length 76 that is at least three times greater than the proximal end's outer diameter 72 but is shorter than an axial length 78 of the rod's distal end 64 .
- the proximal end's larger diameter 72 is nearly the same as the barrel's inner diameter to provide a close slip fit between the two, yet the distal end's relatively small diameter 74 makes it easier to inert and remove the rod 60 without significant drag between the rod 60 and the bore of the barrel 14 .
- the close diametric fit along with the magnitude of the proximal end's axial length 76 limits how far the muzzle retainer's front arm 56 can tilt upward away from the barrel 14 and the breech retainer's rear arm 68 .
- the muzzle retainer's front arm 56 prevents breech retainer 52 from tilting up and off of the pistol's breech end 26 .
- the muzzle retainer's front arm 56 holds the breech retainer's rear arm 68 securely down against the pistol's action mechanism 36 , thereby preventing the action mechanism 36 from operating when the gun-locking device 10 a is in the locked configuration.
- gun-locking device 10 a include a lock 80 to secure the muzzle retainer 50 to the breech retainer 52 , and thus prevent an unauthorized person from using the pistol 12 when the gun-locking device 10 a is in the locked configuration.
- Lock 80 represents any means for locking the muzzle retainer 50 to the breech retainer 52 .
- Some examples of lock 80 are in the form of a padlock.
- Some examples of lock 80 are integrally incorporated in gun-locking device 10 itself.
- Some example means for operating lock 80 include entering a combination, turning a key, reading an RFID device, reading a fingerprint, reading a magnetic field, etc.
- FIG. 3 shows an example of the lock 80 being in an unlocked state.
- FIGS. 1 and 2 show an example of the lock 80 being in a locked state.
- the muzzle retainer 50 includes a front tab 82
- the breech retainer 52 includes a rear tab 84 .
- the lock 80 secures the front tab 82 to the rear tab 84 when the gun-locking device 10 a is in the locked configuration.
- At least one of the muzzle retainer 50 and the breech retainer 52 defines a cavity 86 (e.g., a recess, a pocket, etc.) in which the lock 80 can be compactly stored while the lock 80 is in the locked state.
- the lock 80 is less likely to flop around.
- the lock 80 is movable selectively in and out of the cavity 86 while the gun-locking device 10 a is in the locked configuration.
- FIG. 1 shows the lock 80 held in the cavity 86
- FIG. 2 shows the lock 80 having been swung out from within the cavity 86 . Being able to swing the lock 80 out from within the cavity 86 makes it easier to open and close the lock 80 .
- muzzle retainer 50 include a plurality of knuckle knobs 88 below the cavity 86 .
- the knuckle knobs 88 help define cavity 86 and provide one or more protrusion for a user's hand to push against when moving the muzzle retainer 50 .
- gun-locking device 10 a include additional features that make it more functional and/or more protective of the pistol's surface finish.
- Some examples of gun-locking device 10 a include a non-metallic or polymeric ring 90 (e.g., a rubber O-ring, an annular gasket, etc.) encircling the rod's proximal end 62 to prevent the muzzle retainer 50 from scratching the muzzle end 22 of the pistol 12 .
- Some examples of gun-locking device 10 a include a magnet 92 on the muzzle retainer's front member 54 and/or on the breech retainer's rear member 66 to help hold the muzzle retainer 50 and the breech retainer 52 in place while the lock 80 is being installed.
- Some examples of gun-locking device 10 a include a non-metallic liner 94 on at least one of the muzzle retainer 50 and the breech retainer 52 to prevent the gun-locking device 10 a from scratching various surfaces of the pistol 12 .
- Gun-locking device 10 a can be custom designed to fit different firearms.
- FIG. 5 shows the gun-locking device 10 b comprising a muzzle retainer 50 ′ and a breech retainer 52 ′, which correspond to the muzzle retainer 50 and the breech retainer 52 , respectively.
- the gun-locking device 10 b of FIG. 5 , is very similar to the gun-locking device 10 a , of FIGS. 1-4 , but is sized and shaped to fit the revolver 96 rather than the pistol 12 .
- the revolver 96 includes a cylinder 98 containing a series of chambers 100 .
- Rotating the cylinder 98 selectively places one of the chambers 100 in collinear alignment with the revolver's barrel 102 , whereby the aligned chamber 100 becomes a firing chamber.
- a rod 60 ′ of the muzzle retainer 50 ′ extends into the one firing chamber 100 that is aligned with the barrel 60 ′, thereby ensuring that the aligned firing chamber 100 is completely empty or at least void of a bullet 46 .
- the gun-locking device 10 c is designed to fit even a long gun 104 (e.g., a rifle or a shotgun) with a barrel length of at least sixteen inches. It should be clear, of course, that the gun-locking device 10 c can be of any size and length to fit other firearms 15 , such as handguns, pistols with striker-fired firing pins, pistols with hammer-fired firing pins, and revolvers.
- the long gun 104 comprises a barrel 106 with a muzzle end 108 , a firing chamber 110 , an action mechanism 112 , a trigger 114 , and a stock 116 .

- the sleeve 118 defines a hole 124 for receiving the lock 80 .
- the sleeve 118 includes a collet 126 and a flange 128 .
- the collet 126 has a collet diameter that varies between an expanded diameter 130 and a relaxed diameter 132 , wherein the expanded diameter 130 is greater than a barrel diameter 134 , and the relaxed diameter 132 is less than the barrel diameter 134 .
- the firing chamber 110 has a chamber diameter 125 that is sufficient to contain a cartridge case 48 and a bullet 46 prior to the bullet 46 being fired.
- the chamber diameter 125 is larger than the barrel diameter 134 , thus the collet 126 can expand radially within the firing chamber 110 .
- the rod 120 is elongate in the axial direction 122 .
- the rod 120 defines a cavity 136 that provides clearance for the lock 80 .
- Some examples of cavity 136 include a groove, a detent, an aperture, a hole, a notch, etc.
- the rod 120 includes a head 138 and a handle 140 .
- the gun-locking device 10 c is configurable selectively in a locked configuration ( FIG. 10 ) and a released configuration ( FIG. 6 ).
- the locked configuration the flange 128 engages the muzzle end 108 , the collet 126 extends into the firing chamber 110 , the head 138 forces the collet 126 radially outward to the expanded diameter 130 , and the hole 124 in the sleeve 118 is aligned with the cavity 136 in the rod 120 with respect to the axial direction 122 .
- the sleeve 118 in the released configuration, is spaced apart from the firearm (e.g., the long gun 104 ), the hole 124 in the sleeve 118 is misaligned with the cavity 136 in the rod 120 with respect to the axial direction 122 , and the collect 126 is at the relaxed diameter 132 .
- the gun-locking device 10 c can be reconfigured from the released configuration to the locked configuration by following the example steps illustrated sequentially in FIGS. 6-10 .
- FIG. 6 shows a live cartridge 40 in the firing chamber 110 , so the cartridge 40 would first need to be removed to provide room for the gun-locking device 10 c to extend into the firing chamber 110 .
- FIG. 6 shows the rod's head 138 and the sleeve's collect 126 being axially offset, which leaves the collet 126 at the relaxed diameter 132 for easily inserting the sleeve 118 and the rod 120 into the barrel 106 .
- FIG. 7 shows the firing chamber 110 empty.
- FIG. 7 also shows the gun-locking device 10 c being slid into the barrel 106 .
- FIG. 8 shows the sleeve's flange 128 abutting the muzzle end 108 , which indicates that the gun-locking device 10 c is fully inserted into the barrel 106 and extends into the firing chamber 110 .
- the sleeve's flange 128 abutting the muzzle end 108 thus provides a visual indicator that the firing chamber 110 is empty.
- FIG. 9 shows the rod 120 partly withdrawn from sleeve 118 , whereby the rod's handle 140 is now axially spaced apart from the sleeve 118 .
- the rod's head 138 has forced the collect 126 to its expanded diameter 130 .
- the collect 126 is shown having expanded radially into the firing chamber 110 and is now too large to pull back out through the barrel 106 , as the barrel diameter 134 is smaller than the collet's expanded diameter 130 .
- the rod's cavity 136 becomes aligned with the sleeve's hole 124 to allow the insertion of the lock 80 .
- the cavity 136 is in the form of a groove fully encircling the rod 120 .
- the rod 120 and the sleeve 118 do not have to be in any particular rotational relationship in order to insert the lock 80 .
- FIG. 10 shows the lock 80 having been inserted through the hole 124 and the cavity 136 .
- FIG. 10 thus shows gun-locking device 10 c in its locked configuration.
- the gun-locking device 10 d is designed to fit even a long gun 104 (e.g., a rifle or a shotgun) with a barrel length of at least sixteen inches. It should be clear, of course, that the gun-locking device 10 d can be of any size and length to fit other firearms 15 , such as handguns, pistols and revolvers.

Abstract
A firearm inhibiting device and method of using the same is disclosed which will only mount onto the firearm if the firing chamber is empty of ammunition (a live cartridge). Further inhibiting, for handguns the device prevents operation of the gun's action mechanism. Further inhibiting, for long-guns the device prevents a live cartridge from entering the firing chamber. The empty chamber indication is unique in that it will indicate an empty firing chamber while the action is prevented from operation and in the battery position.
Description
- This application is a continuation-in-part of co-pending patent application Ser. No. 17/318,235 filed on May 12, 2021.
- This patent generally pertains to firearms and more specifically to devices and methods for inhibiting the firearm's unauthorized use or accidental discharge.
- A firearm (also known as a gun) is an apparatus comprising a barrel, an action mechanism, and a firing chamber from which one or more projectiles are propelled by an explosive. The firing chamber at a breech end of the barrel is where a live cartridge is situated just prior to firing. The terms, “firing” and “discharging” are used interchangeably. A cartridge comprises a cartridge case containing the explosive and holds the bullet or projectile(s). When fired, the explosive propels the bullet out through a muzzle end of the barrel. Depending on the type of firearm, the action mechanism provides one or more functions. Examples of such functions include firing the gun, ejecting the spent cartridge case after firing, and/or reloading the next live cartridge into the firing chamber.
- Many firearms can be classified in one of two categories, a handgun and a long gun. The term, “long gun,” as used herein, refers to any firearm with a barrel length of at least sixteen inches. Some long guns include a stock for bracing the firearm against a shooter's shoulder. The term, “handgun,” as used herein, refers to any firearm with a barrel length of less than sixteen inches.
- Many long guns can be further classified in one of two categories, a rifle and a shotgun. The term, “rifle,” as used herein, refers to a long gun having a barrel with a helically grooved bore, known as rifling. Rifles typically fire a projectile or bullet that prior to firing is attached to and projects forward from a cartridge case. Many long guns utilize a variety of types of action mechanisms (e.g., bolt action, lever action, pump action, etc.).
- The term, “shotgun,” as used herein, refers to a long gun having a barrel with usually a smooth bore. Shot guns typically fire one or more projectiles that prior to firing are enclosed within a cartridge case.
- Many handguns can be further classified in one of two categories, a pistol and a revolver. The term, “pistol,” as used herein, refers to a handgun with a single firing chamber. Pistols typically include a striker-fired firing pin or a hammer-fired firing pin. In a pistol the firing chamber is usually integral to the barrel. In a pistol, the action mechanism includes a slide that moves a live cartridge into the firing chamber and ensures the action mechanism is in battery position, then fires it (e.g., via a hammer or striker-fired pin), and then ejects the case from the firing chamber. The battery position is when the cartridge is ready to be fired and a breech cover is in position to fire the live cartridge. With a pistol, bullets are discharged sequentially from the same firing chamber.
- The term, “revolver,” as used herein, refers to a handgun with a revolving cylinder containing a series of chambers. When rotation of the cylinder places one of the chambers in collinear alignment with the breech end of the barrel, the aligned chamber becomes the firing chamber. In a revolver, the firing chamber is separate from the barrel, but at the breech end and is in alignment with the barrel. The action mechanism of a revolver is the cylinder with its associated mechanism that rotates the next chamber into battery position, fires it, and then rotates that chamber out of battery position while bringing in the next chamber to battery position. Initially, each firing chamber is loaded with a live cartridge. After firing a live cartridge, the revolver's action mechanism rotates the cylinder to move the chamber with the spent cartridge away from the breech end of the barrel and move the next chamber with a live cartridge in its place to be fired at the next shot.
- Various devices are available for inhibiting unauthorized use of a firearm and for preventing it from being accidentally discharged. Such devices typically disable one or more functional elements of a firearm. Examples of such functional elements include the firearm's trigger, barrel and hammer.

FIGS. 1-20 show example gun-locking devices 10 (e.g., gun-locking devices firearm 15 and preventing it from being accidentally discharged. The term, “firearm,” as used herein, refers to any apparatus comprising a barrel, an action mechanism, and a firing chamber from which one or more projectiles (e.g., a bullet, shot, etc.) are propelled by an explosive. Some examples offirearm 15 include a pistol 12 (e.g., a hammer or a striker fired), arevolver 96, and a long gun 104 (e.g., a rifle or a shotgun). Each gun-lockingdevice 10 includes a rod extending through a barrel of thefirearm 15 and into the firing chamber to ensure there is no bullet or live cartridge in the chamber. - In the example shown in
FIGS. 1-4 , the gun-lockingdevice 10 a is attachable to thepistol 12 with abarrel 14 that is less than 16 inches long. In this example, thepistol 12 comprises aframe 16, agrip 18, thebarrel 14, afront sight 20 at amuzzle end 22, arear sight 24 at abreech end 26, ahammer 28 at thebreech end 26, atrigger 30, atrigger guard 32, a firingchamber 34 defined by at least one of theframe 16 and thebarrel 14, and an action mechanism 36 (e.g., a slide action). Theaction mechanism 36 is movably attached to theframe 16 to (a) enable firing of thepistol 12, (b) eject a spentcartridge case 38 after firing, and (c) reload a nextlive cartridge 46 into the firingchamber 34. In some examples, thepistol 12 includes afiring pin 42 for delivering the hammer's impact to a primer of alive cartridge 40 when loaded in the firingchamber 34. In some examples of thepistol 12, a striker-fired firing pin (without the hammer 28) is what delivers an impact to the primer. - Some examples of
pistol 10 a include amagazine 44 for feedinglive cartridges 40 individually to the firingchamber 34. In some examples, eachcartridge 40 comprises abullet 46 attached to the front end of acartridge case 48.FIG. 4 happens to show an empty spentcartridge case 38 in firingchamber 34. In some examples, the firingchamber 34 at times is completely empty. In some examples, the firingchamber 34 contains alive cartridge 40 with thebullet 46 still attached to thecartridge case 48. - In some examples, as shown in
FIGS. 1-4 , gun-lockingdevice 10 a comprises amuzzle retainer 50 and abreech retainer 52. In some examples, themuzzle retainer 50 comprises afront member 54 and afront arm 56. In some examples, thefront arm 56 has a frontdistal end 58 extending rearward from thefront member 54. Some examples of gun-lockingdevice 10 a include arod 60 with aproximal end 62 and adistal end 64, wherein theproximal end 62 is adjacent and attached to thefront member 54 of themuzzle retainer 50. In some examples, the rod'sdistal end 64 extends rearward away from thefront member 50. - In some examples, the
breech retainer 52 comprises arear member 66 and arear arm 68. In some examples, therear arm 68 has adistal end 70 extending forward from therear member 66. - In some examples, gun-locking
device 10 a is configurable selectively to a locked configuration (FIGS. 1, 2, and 4 ) and a released configuration (FIG. 3 ). In some examples of the locked configuration, thefront member 54 and therear member 66 are slid together to capture thepistol 12 between the gun-locking device'sfront member 54 andrear member 66. - More specifically, in some examples of the locked configuration, the
front member 54 engages the pistol'smuzzle end 22, therear member 66 engages the pistol'sbreech end 26, and thefront arm 56 overlaps both therear arm 68 and thebarrel 14. In some examples, thefront arm 56 and therear arm 68 overlap directly above the pistol'saction mechanism 36 to hold them onto the pistol and thus prevent theaction mechanism 36 from operating. The term, “overlap,” as it pertains to two parts overlapping, refers to one part at least partially covering the other part as viewed from a direction perpendicular to alongitudinal axis 162 of the firearm'sbarrel 14. - In some examples of the locked configuration, the
front member 54 of themuzzle retainer 50 is closer to the rear member's reardistal end 70 than to the front member's frontdistal end 58. In some examples of the locked configuration, the breech retainer'srear member 52 is closer to the front member's frontdistal end 58 than to the rear member's reardistal end 70. - In some examples of the locked configuration, the
rod 60 extends through thebarrel 14 and at least partially into the firingchamber 34 to ensure that the firingchamber 34 is empty or at least void of alive cartridge 40 with an attachedbullet 46. In some examples, the rod'sproximal end 62 has anouter diameter 72 that is larger than anouter diameter 74 of the rod'sdistal end 64. In some examples, the rod'sproximal end 62 has anaxial length 76 that is at least three times greater than the proximal end'souter diameter 72 but is shorter than anaxial length 78 of the rod'sdistal end 64. In some examples, the proximal end'slarger diameter 72 is nearly the same as the barrel's inner diameter to provide a close slip fit between the two, yet the distal end's relativelysmall diameter 74 makes it easier to inert and remove therod 60 without significant drag between therod 60 and the bore of thebarrel 14. - In some examples, the close diametric fit along with the magnitude of the proximal end's
axial length 76 limits how far the muzzle retainer'sfront arm 56 can tilt upward away from thebarrel 14 and the breech retainer'srear arm 68. Thus, in some examples, the muzzle retainer'sfront arm 56 preventsbreech retainer 52 from tilting up and off of the pistol'sbreech end 26. Moreover, in some examples, the muzzle retainer'sfront arm 56 holds the breech retainer'srear arm 68 securely down against the pistol'saction mechanism 36, thereby preventing theaction mechanism 36 from operating when the gun-lockingdevice 10 a is in the locked configuration. - Some examples of gun-locking
device 10 a include alock 80 to secure themuzzle retainer 50 to thebreech retainer 52, and thus prevent an unauthorized person from using thepistol 12 when the gun-lockingdevice 10 a is in the locked configuration.Lock 80 represents any means for locking themuzzle retainer 50 to thebreech retainer 52. Some examples oflock 80 are in the form of a padlock. Some examples oflock 80 are integrally incorporated in gun-lockingdevice 10 itself. Some example means for operatinglock 80 include entering a combination, turning a key, reading an RFID device, reading a fingerprint, reading a magnetic field, etc.FIG. 3 shows an example of thelock 80 being in an unlocked state.FIGS. 1 and 2 show an example of thelock 80 being in a locked state. - In some examples, the
muzzle retainer 50 includes afront tab 82, and thebreech retainer 52 includes arear tab 84. In some examples, thelock 80 secures thefront tab 82 to therear tab 84 when the gun-lockingdevice 10 a is in the locked configuration. - In some examples, at least one of the
muzzle retainer 50 and thebreech retainer 52 defines a cavity 86 (e.g., a recess, a pocket, etc.) in which thelock 80 can be compactly stored while thelock 80 is in the locked state. When stored within thecavity 86, thelock 80 is less likely to flop around. In some examples, thelock 80 is movable selectively in and out of thecavity 86 while the gun-lockingdevice 10 a is in the locked configuration.FIG. 1 , for example, shows thelock 80 held in thecavity 86, andFIG. 2 shows thelock 80 having been swung out from within thecavity 86. Being able to swing thelock 80 out from within thecavity 86 makes it easier to open and close thelock 80. - Some examples of
muzzle retainer 50 include a plurality ofknuckle knobs 88 below thecavity 86. In some examples, the knuckle knobs 88 help definecavity 86 and provide one or more protrusion for a user's hand to push against when moving themuzzle retainer 50. - Some examples of gun-locking
device 10 a include additional features that make it more functional and/or more protective of the pistol's surface finish. Some examples of gun-lockingdevice 10 a include a non-metallic or polymeric ring 90 (e.g., a rubber O-ring, an annular gasket, etc.) encircling the rod'sproximal end 62 to prevent themuzzle retainer 50 from scratching themuzzle end 22 of thepistol 12. Some examples of gun-lockingdevice 10 a include amagnet 92 on the muzzle retainer'sfront member 54 and/or on the breech retainer'srear member 66 to help hold themuzzle retainer 50 and thebreech retainer 52 in place while thelock 80 is being installed. Some examples of gun-lockingdevice 10 a include anon-metallic liner 94 on at least one of themuzzle retainer 50 and thebreech retainer 52 to prevent the gun-lockingdevice 10 a from scratching various surfaces of thepistol 12. - Gun-locking
device 10 a can be custom designed to fit different firearms.FIG. 5 , for example, shows the gun-lockingdevice 10 b comprising amuzzle retainer 50′ and abreech retainer 52′, which correspond to themuzzle retainer 50 and thebreech retainer 52, respectively. The gun-lockingdevice 10 b, ofFIG. 5 , is very similar to the gun-lockingdevice 10 a, ofFIGS. 1-4 , but is sized and shaped to fit therevolver 96 rather than thepistol 12. - In some examples, the
revolver 96 includes acylinder 98 containing a series ofchambers 100. Rotating thecylinder 98 selectively places one of thechambers 100 in collinear alignment with the revolver'sbarrel 102, whereby the alignedchamber 100 becomes a firing chamber. When gun-lockingdevice 10 b is in the locked configuration, as shown inFIG. 5 , arod 60′ of themuzzle retainer 50′ extends into the onefiring chamber 100 that is aligned with thebarrel 60′, thereby ensuring that the alignedfiring chamber 100 is completely empty or at least void of abullet 46. - In the example shown in
FIGS. 6-14 , the gun-lockingdevice 10 c is designed to fit even a long gun 104 (e.g., a rifle or a shotgun) with a barrel length of at least sixteen inches. It should be clear, of course, that the gun-lockingdevice 10 c can be of any size and length to fitother firearms 15, such as handguns, pistols with striker-fired firing pins, pistols with hammer-fired firing pins, and revolvers. In the illustrated example, thelong gun 104 comprises abarrel 106 with amuzzle end 108, afiring chamber 110, anaction mechanism 112, atrigger 114, and astock 116. In some examples, the gun-lockingdevice 10 c extends through thebarrel 106, into thefiring chamber 110, and is locked there to disable the firearm 15 (e.g., long gun 104). - In some examples, the gun-locking
device 10 c comprises asleeve 118 with arod 120 extending through thesleeve 118. In some examples, thesleeve 118 is elongate in anaxial direction 122. In some examples, thesleeve 118 defines ahole 124 for receiving thelock 80. In some examples, thesleeve 118 includes acollet 126 and aflange 128. In some examples, thecollet 126 has a collet diameter that varies between an expandeddiameter 130 and arelaxed diameter 132, wherein the expandeddiameter 130 is greater than abarrel diameter 134, and therelaxed diameter 132 is less than thebarrel diameter 134. - In some examples, the
firing chamber 110 has achamber diameter 125 that is sufficient to contain acartridge case 48 and abullet 46 prior to thebullet 46 being fired. In some examples, thechamber diameter 125 is larger than thebarrel diameter 134, thus thecollet 126 can expand radially within thefiring chamber 110. - In some examples, the
rod 120 is elongate in theaxial direction 122. In some examples, therod 120 defines acavity 136 that provides clearance for thelock 80. Some examples ofcavity 136 include a groove, a detent, an aperture, a hole, a notch, etc. In some examples, therod 120 includes ahead 138 and ahandle 140. - In some examples, the gun-locking
device 10 c is configurable selectively in a locked configuration (FIG. 10 ) and a released configuration (FIG. 6 ). In some examples, in the locked configuration, theflange 128 engages themuzzle end 108, thecollet 126 extends into thefiring chamber 110, thehead 138 forces thecollet 126 radially outward to the expandeddiameter 130, and thehole 124 in thesleeve 118 is aligned with thecavity 136 in therod 120 with respect to theaxial direction 122. - In some examples, in the released configuration, the
sleeve 118 is spaced apart from the firearm (e.g., the long gun 104), thehole 124 in thesleeve 118 is misaligned with thecavity 136 in therod 120 with respect to theaxial direction 122, and the collect 126 is at therelaxed diameter 132. - In some examples, the gun-locking
device 10 c can be reconfigured from the released configuration to the locked configuration by following the example steps illustrated sequentially inFIGS. 6-10 .FIG. 6 shows alive cartridge 40 in thefiring chamber 110, so thecartridge 40 would first need to be removed to provide room for the gun-lockingdevice 10 c to extend into thefiring chamber 110.FIG. 6 shows the rod'shead 138 and the sleeve's collect 126 being axially offset, which leaves thecollet 126 at therelaxed diameter 132 for easily inserting thesleeve 118 and therod 120 into thebarrel 106. -
FIG. 7 shows thefiring chamber 110 empty.FIG. 7 also shows the gun-lockingdevice 10 c being slid into thebarrel 106. -
FIG. 8 shows the sleeve'sflange 128 abutting themuzzle end 108, which indicates that the gun-lockingdevice 10 c is fully inserted into thebarrel 106 and extends into thefiring chamber 110. The sleeve'sflange 128 abutting themuzzle end 108 thus provides a visual indicator that thefiring chamber 110 is empty. -
FIG. 9 shows therod 120 partly withdrawn fromsleeve 118, whereby the rod'shandle 140 is now axially spaced apart from thesleeve 118. In this position, the rod'shead 138 has forced the collect 126 to its expandeddiameter 130. The collect 126 is shown having expanded radially into thefiring chamber 110 and is now too large to pull back out through thebarrel 106, as thebarrel diameter 134 is smaller than the collet's expandeddiameter 130. Whenrod 120 has been pulled to radially expand thecollet 126, as shown inFIG. 9 , the rod'scavity 136 becomes aligned with the sleeve'shole 124 to allow the insertion of thelock 80. In some examples, thecavity 136 is in the form of a groove fully encircling therod 120. With thecavity 136 being a circular groove, therod 120 and thesleeve 118 do not have to be in any particular rotational relationship in order to insert thelock 80. -
FIG. 10 shows thelock 80 having been inserted through thehole 124 and thecavity 136.FIG. 10 thus shows gun-lockingdevice 10 c in its locked configuration. - In the example shown in
FIGS. 15-17 , the gun-lockingdevice 10 d is designed to fit even a long gun 104 (e.g., a rifle or a shotgun) with a barrel length of at least sixteen inches. It should be clear, of course, that the gun-lockingdevice 10 d can be of any size and length to fitother firearms 15, such as handguns, pistols and revolvers. In the illustrated example, thelong gun 104 comprises thebarrel 106 with themuzzle end 108, thefiring chamber 110, theaction mechanism 112, thetrigger 114, and atrigger guard 142. In some examples, the gun-lockingdevice 10 d extends through thebarrel 106, into thefiring chamber 110, and is locked there to disable thefirearm 15. - In some examples, the gun-locking
device 10 d comprises amuzzle retainer 142 that includes afront member 144 and arod 146 extending from thefront member 144. In some examples, the gun-lockingdevice 10 d comprises aconnector 148, thelock 80, and a pliableelongate member 150 extending between themuzzle retainer 142 and theconnector 148. Some examples of the pliableelongate member 150 include a plastic coated metal cable, a wire, a chain, etc. - In some examples, the gun-locking
device 10 d is configurable selectively to a locked configuration (FIG. 17 ) and a released configuration (FIG. 15 ). In some examples, in the locked configuration, thefront member 144 of themuzzle retainer 142 engages themuzzle end 108, therod 146 extends through thebarrel 106 and into thefiring chamber 110 of the firearm (e.g., the long gun 104), theconnector 148 is attached to thetrigger guard 142, and thelock 80 is attached to the pliableelongate member 150 and/or theconnector 148. In some examples, in the released configuration, themuzzle retainer 142 is spaced apart from the firearm (e.g., the long gun 104). - In some examples, the
connector 148 includes atoggle arm 152 that is movable selectively to a taut position (FIG. 17 ) and a loose position (FIGS. 15 and 16 ), wherein the pliableelongate member 150 is held in greater tension when thetoggle arm 152 is in the taut position than in the loose position while the gun-lockingdevice 10 d is in the locked configuration. - In some examples, the gun-locking
device 10 d can be reconfigured from the released configuration to the locked configuration by following the example steps illustrated sequentially inFIGS. 15, 16, and 17 .FIG. 15 shows thelive cartridge 40 in thefiring chamber 110, so thecartridge 40 would first need to be removed to provide room for the gun-lockingdevice 10 d to extend into thefiring chamber 110.FIG. 15 shows gun-lockingdevice 10 d in the released configuration spaced apart from thelong gun 104. -
FIG. 16 shows therod 146 having been inserted into thebarrel 106 such that therod 146 extends into thefiring chamber 110. In some examples, the muzzle retainer'sfront member 144 abutting themuzzle end 108 provides an indicator that therod 146 is extending into thefiring chamber 110, and thus thefiring chamber 110 is empty. In some examples, theconnector 148 includes ahook 154. In the illustrated example,FIG. 16 shows theconnector 148 being hooked onto the trigger guard 142 (and/or hooked onto the trigger 114).FIG. 16 also shows thetoggle arm 152 in the loose position. In the loose position, pliableelongate member 150 is loose to allow thehook 154 to be readily hooked onto thetrigger guard 142. -
FIG. 17 shows thetoggle arm 152 having been swung over to the taut position to place the pliableelongate member 150 in tension. In some examples, thelock 80 is installed (installed position) to hold thetoggle arm 152 at its taut position and thus hold gun-lockingdevice 10 d at its locked configuration. In some examples, thelock 80 in the installed position (shown inFIG. 17 ) fastens afirst tab 156 ontoggle arm 152 to asecond tab 158 on abase 160 of theconnector 148. In some examples, thelock 80 in a removed position (FIGS. 15 and 16 ) enables thetoggle arm 152 to move from the taut position to the loose position. -
FIGS. 18-20 show an example gun-lockingdevice 10 e.FIG. 18 shows gun-lockingdevice 10 e in a released configuration.FIG. 20 shows gun-lockingdevice 10 e in a locked configuration.FIG. 19 is similar toFIG. 20 but with thelock 80 not yet attached. - The gun-locking
device 10 e ofFIGS. 18-20 , is similar to the gun-lockingdevice 10 a, ofFIGS. 1-4 , in that gun-lockingdevice 10 e comprises amuzzle retainer 164 and abreech retainer 166. In the illustrated example, themuzzle retainer 164 includes afront member 168 and afront arm 170, and thebreech retainer 166 includes arear member 172 and arear arm 174. - In this example, a
hinge 176 allows therear member 172 to pivot 178 about ahinge pin 180 ofhinge 176. Thehinge 176 allows gun-lockingdevice 10 e to be swung open or closed for respectively removing or attaching gun-lockingdevice 10 e to the firearm 15 (e.g.,pistol 12 or revolver 96) - In some examples, the
hinge pin 180 extends along thelateral axis 162 through thefront arm 170 and therear arm 174, and thereby couples thefront arm 170 in an engaged relationship with therear arm 174. The term, “engaged relationship,” as relates to two parts being in engaged relationship means that the two parts are connected and/or contacting each other. - A
lateral axis 182 along which thehinge pin 180 lies, in some examples, lies perpendicular to thelongitudinal axis 162 and avertical axis 184. Thelongitudinal axis 162 is defined by the longitudinal centerline of thebarrel 14 when thefirearm 15 is attached and locked to the gun-locking device. Thevertical axis 184 is perpendicular to thelongitudinal axis 162 and lies on an imaginary plane along which thebarrel 14 and thegrip 18 lie. - In some examples, the
lock 80 has selectively a locked state (FIG. 20 ) and an unlocked state (FIGS. 18 and 19 ). When thelock 80 is attached to the gun-lockingdevice 10 e and thelock 80 is in the locked state, thelock 80 prevents the gun-lockingdevice 10 e from moving between the locked configuration and the released configuration.
