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.
In the example shown in
Some examples of pistol 10a include a magazine 44 for feeding live cartridges 40 individually to the firing chamber 34. In some examples, each cartridge 40 comprises a bullet 46 attached to the front end of a cartridge case 48.
In some examples, as shown in
In some examples, the breech retainer 52 comprises a rear member 66 and a rear arm 68. In some examples, the rear arm 68 has a distal end 70 extending forward from the rear member 66.
In some examples, gun-locking device 10a is configurable selectively to a locked configuration (
More specifically, in some examples of the locked configuration, the front member 54 engages the pistol's muzzle end 22, the rear member 66 engages the pistol's breech end 26, and the front arm 56 overlaps both the rear arm 68 and the barrel 14. In some examples, 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. 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 a longitudinal axis 162 of the firearm's barrel 14.
In some examples of the locked configuration, 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. In some examples of the locked configuration, 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.
In some examples of the locked configuration, 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. In some examples, 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. In some examples, 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. In some examples, 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.
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's front arm 56 can tilt upward away from the barrel 14 and the breech retainer's rear arm 68. Thus, in some examples, the muzzle retainer's front arm 56 prevents breech retainer 52 from tilting up and off of the pistol's breech end 26. Moreover, in some examples, 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 10a is in the locked configuration.
Some examples of gun-locking device 10a 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 10a 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.
In some examples, the muzzle retainer 50 includes a front tab 82, and the breech retainer 52 includes a rear tab 84. In some examples, the lock 80 secures the front tab 82 to the rear tab 84 when the gun-locking device 10a is in the locked configuration.
In some examples, 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. When stored within the cavity 86, the lock 80 is less likely to flop around. In some examples, the lock 80 is movable selectively in and out of the cavity 86 while the gun-locking device 10a is in the locked configuration.
Some examples of muzzle retainer 50 include a plurality of knuckle knobs 88 below the cavity 86. In some examples, 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.
Some examples of gun-locking device 10a include additional features that make it more functional and/or more protective of the pistol's surface finish. Some examples of gun-locking device 10a 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 10a 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 10a 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 10a from scratching various surfaces of the pistol 12.
Gun-locking device 10a can be custom designed to fit different firearms.
In some examples, 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. When gun-locking device 10b is in the locked configuration, as shown in
In the example shown in
In some examples, the gun-locking device 10c comprises a sleeve 118 with a rod 120 extending through the sleeve 118. In some examples, the sleeve 118 is elongate in an axial direction 122. In some examples, the sleeve 118 defines a hole 124 for receiving the lock 80. In some examples, the sleeve 118 includes a collet 126 and a flange 128. In some examples, 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.
In some examples, 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. In some examples, the chamber diameter 125 is larger than the barrel diameter 134, thus the collet 126 can expand radially within the firing chamber 110.
In some examples, the rod 120 is elongate in the axial direction 122. In some examples, 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. In some examples, the rod 120 includes a head 138 and a handle 140.
In some examples, the gun-locking device 10c is configurable selectively in a locked configuration (
In some examples, in the released configuration, the sleeve 118 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.
In some examples, the gun-locking device 10c can be reconfigured from the released configuration to the locked configuration by following the example steps illustrated sequentially in
In the example shown in
In some examples, the gun-locking device 10d comprises a muzzle retainer 142 that includes a front member 144 and a rod 146 extending from the front member 144. In some examples, the gun-locking device 10d comprises a connector 148, the lock 80, and a pliable elongate member 150 extending between the muzzle retainer 142 and the connector 148. Some examples of the pliable elongate member 150 include a plastic coated metal cable, a wire, a chain, etc.
In some examples, the gun-locking device 10d is configurable selectively to a locked configuration (
In some examples, the connector 148 includes a toggle arm 152 that is movable selectively to a taut position (
In some examples, the gun-locking device 10d can be reconfigured from the released configuration to the locked configuration by following the example steps illustrated sequentially in
The gun-locking device 10e of
In this example, a hinge 176 allows the rear member 172 to pivot 178 about a hinge pin 180 of hinge 176. The hinge 176 allows gun-locking device 10e to be swung open or closed for respectively removing or attaching gun-locking device 10e to the firearm 15 (e.g., pistol 12 or revolver 96)
In some examples, the hinge pin 180 extends along the lateral axis 162 through the front arm 170 and the rear arm 174, and thereby couples the front arm 170 in an engaged relationship with the rear 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 the hinge pin 180 lies, in some examples, lies perpendicular to the longitudinal axis 162 and a vertical axis 184. The longitudinal axis 162 is defined by the longitudinal centerline of the barrel 14 when the firearm 15 is attached and locked to the gun-locking device. The vertical axis 184 is perpendicular to the longitudinal axis 162 and lies on an imaginary plane along which the barrel 14 and the grip 18 lie.
In some examples, the lock 80 has selectively a locked state (
