ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to safety mechanisms for firearms, both elongated firearms, such as shotguns, rifles, bazookas, rocket launchers, grenade launchers and other military small arms, as well as, handguns, especially for military personnel and law enforcement officers. The present invention firearm system involves an engagement assembly affixed to handwear, e.g. a glove, which must be inserted into a mechanism in the firearm before the firearm may be discharged.
2. Information Disclosure Statement
U.S. Patent No. 4,672,763 to Jerry M. Cunningham describes a safety device for preventing the unauthorized firing of a weapon, such as a pistol. The device has a hammer, a handle, and a leaf spring inside of the handle. The leaf spring places tension on the hammer, when the weapon is enabled. The leaf spring is held by a stop member, which is movable. When the stop member is moved to a lower position, the spring is released, and the weapon is disabled. The stop member is moved by a strap and a ring, connected to the stop member. The handle must be taken apart in order to return the spring and the stop member to the enabled condition.
U.S. Patent No. 4,833,811 to Earl Wilkinson describes a safety for hammer-equipped pistols, which includes a lock pin slidably mounted in the handle of a pistol, a companion lock pin spring biasing the lock pin inwardly of the handle toward the hammer, a locking rod slidably mounted in the handle in angular relationship with respect to the lock pin, the upper end of which locking rod is adapted to normally engage a seat provided in the lock pin and a release pin normally located in a release pin seat provided in the base of the handle, for engaging the opposite, or lower end of the locking rod and preventing relative movement between the locking rod and the lock pin. In a preferred embodiment, one end of a release pin cable is attached to the release pin and the opposite end of the cable is secured to the pistol holder, wherein seizure and extension of the pistol beyond the length of the cable pulls the release pin from the release pin seat and allows the locking rod to slide downwardly inside the pistol handle and facilitate forward projection of the lock pin responsive of the lock pin spring and the locking of the hammer to prevent firing of the pistol.
The apparatus of U.S. Patent No. 4,967,502 to Terry M. Vernon is adapted to be used in a firearm of the type having a body having an interior space, a hammer supported by the body for movement, and a trigger for actuating the hammer. A strut member is located in the interior space of the body and has one end pivotally connected to the hammer. A capsule is provided having first and second ends and a spring means located therein. Opening means is formed at the first end of said capsule whereby the spring means may be compressed by applying force to the spring means by way of said opening means. The capsule is adapted to be supported by the body in a given position relative to the second end of the strut member whereby the other end of the strut member will apply force to the spring means, by way of said opening means to allow sufficient spring compression to occur such that the hammer will fire the firearm when actuated by the trigger. Means is provided for releasably holding the capsule in the given position for firing purposes and for allowing the capsule to be released from the given position for releasing spring compression to disable the firearm. In one embodiment, the capsule is completely removable from the firearm. In another embodiment, a releasable keeper is provided which is movable into an opening for engaging the other end of the capsule for moving the capsule to the given position and for holding the capsule in the given position for firing purposes. The keeper may be released to allow the capsule to be moved away from the given position for disabling purposes.
U.S. Patent No. 5,361,525 to Kenneth E. Bowes describes an improved gun safety lock which employs a barrel key to enable the firing mechanism of the gun. The barrel key is inserted in the handle of the gun to allow the hammer of the weapon to be moved into a cocked or firing position. The barrel key is unique for each gun. The barrel key is held in the gun by retaining lugs. A lanyard attaches to the barrel key on one end and to the owner of the gun on the other end. Pressure on the lanyard causes the key to pull out of the gun and thereby disables the gun.
U.S. Patent No. 5,671,560 to Yehuda Meller describes a firearm including a frame having a grip for manually grasping the firearm, a control member movable to enable firing the firearm, a locking device including a latch element movable by an-inserted key either to a locking position or a releasing position, and a locking member movably carried by the frame. A spring urges the locking member into contact with the control member such that the locking member moves with the control member to enable firing the firearm. The locking member is located with respect to the latch element of the locking device so as to be engaged thereby when the latch element is in its locking position, to block the movement of the locking member, and thereby to prevent the firing of the firearm when the latch element is in its locking position. Two embodiments are described: a semi-automatic pistol, wherein the control member is a pivotal safety lever; and a revolver, wherein the control member is a rebound slide.
U.S. Patent No. 5,915,936 to John Charles Brentzel describes a firearm with an identification safety system for preventing use by an unauthorized user. The firearm includes a barrel for discharging the firearm therethrough, a butt section connected to the barrel, a trigger connected between the barrel and butt section for initiating discharge of the firearm and a safety switch operable between a first position preventing discharge of the firearm and a second position allowing discharge of the firearm. A pressure sensor is positioned in the butt section for sensing grasping of the butt section by a palm of a user and a scanning sensor is connected for scanning a palm print of the palm of the user and generating a data signal representative of the scanned palm print upon sensing grasping of the butt section by the pressure sensor. A memory unit stores data signals representative of the palm prints of authorized users and a microprocessor is connected to both the scanning sensor and the memory unit for receiving the data signal from the scanning sensor and comparing the received data signal to the data signals stored in the memory unit. The microprocessor controls the safety switch to operate in the first position upon determining the received data signal does not match any of the data signals stored in the memory unit and controls the safety switch to operate in the second position upon determining the received data signal matches one of the data signals stored in the memory unit.
U.S. Patent No. 5,987,796 to Frank Brooks describes a firearm safety mechanism having a self-contained locking mechanism incorporated into the magazine of a semi-automatic pistol which inhibits use of the firearm when a locking mechanism disarms the firing mechanism as well as locking the magazine in position so as to prevent unauthorized replacement. The firearm can be locked against unauthorized use and unlocked by an authorized user without resort to external accessories.
