Definitions

  • the invention is within the broad field of firearm safety devices and more specifically within the field of locking devices which restrict or prevent the unauthorized use of a firearm.
  • Firearm locks come in generally four (4) categories; these are: the padlock; the cable lock; the trigger lock; and, the lock box.
  • Padlocks such as that illustrated in FIG. 3A, are available from a number of manufacturers such as Sturm, Ruger & Company of Southport, Connecticut and Master Lock Company of Milwaukee, Wisconsin. Padlocks are used to secure lockboxes containing handguns, or if the stem is sufficiently long, can be passed through a firing chamber or other access port.
  • Cable locks such as that illustrated in FIG. 3B, are also available from a variety of manufacturers such as Sturm, Ruger or Master Lock.
  • Cable locks are popular because they are flexible, accessed in a variety of ways depending upon model (key, combination, or biometrics), and can be easily passed through a chamber or ejection port of a rifle or handgun.
  • Trigger locks that fit over the trigger guard of a handgun, such as that illustrated in FIG. 3C, are the common form of handgun lockup. These too, are available from a number of manufacturers or suppliers such as Master Lock or Noble Security Systems, Inc. of Encino, California. Lock boxes come in a variety of types that include simple boxes with key locks, wall mounted locks and sleeves,, and biometric scan access only boxes from such manufacturers as Smith & Wesson Corp. of Springfield, Massachusetts.
  • U.S. Patent No. 6,269,576 Bl for a DISABLEMENT MECHANISM FOR A FIREARM issued August 7, 2001 to Charles David Williams (the '576 patent) disclosed a mechanism for disabling a firearm by providing a body positionable to come into contact with the hammer spring assembly.
  • the device is a safety device in that while it prevents the hammer from striking the firing pin and discharging the weapon, the '576 patent does not prevent unauthorized use of the weapon, it merely prevents an accidental use or discharge.
  • Biometrics has long been used to provide security at building or passage access ways. Biometrics involves the use of a scanner to detect an individual's biometric characteristics (thumbprints and retina scans are the most common) and then compares those characteristics to some other pre-recorded data to determine whether or not the individual matches a particular profile. With respect to firearms, biometrics is being used in the hand grips of handguns. The scanner in the grip scans the fingerprint of the user and compares it with the stored fingerprints of allowed users, if there is no match then the gun remains diabled. The disadvantage to this system is the sensitivity of the scanner which reduces its effectiveness in harsh environments and the cost.
  • Biometrics is additionally employed in lock boxes such as that described in U.S. Patent No. 6,260,300 Bl for a BIOMETRICALLY ACTIVATED LOCK AND ENABLEMENT SYSTEM issued July 17, 2001 to Klebes et al. (the '300 patent).
  • Locking boxes such as the '300 patent are effective, but cumbersome if moved.
  • Locking sleeves such as that described in U.S. Patent No. 6,260,299 Bl for a FIREARMS SECURITY DEVICE AND SYSTEM, issued July 17, 2001 to Albert Raymond Jordan, cannot be moved at all and are not convenient for a weapon that is to be transported.
  • one aspect of the present invention described and claimed herein is the provision of a trigger locking mechanism integrated with its host firearm.
  • a further aspect of the present invention is the provision of a trigger locking mechanism that is easily engaged by the firearm user.
  • the present invention is a method and system for providing a firearm safety lock.
  • the trigger guard is slidably mounted in the firearm (can be a revolver, semi-automatic or automatic firearm) frame thus allowing the trigger guard to slide from a home position to a locking position.
  • a locking mechanism is mounted on the forward end of the trigger guard, so that by sliding the trigger guard forward the locking mechanism is brought into a locking position and the lock can be engaged so as to prevent the trigger guard from sliding backward.
  • a trigger mounted in the frame can be pulled back to cause the firearm to fire.
  • the trigger guard is in the locking or forward position, then the trigger cannot be pulled back and the firearm cannot be fired.
  • the locking mechanism itself can be accessed by any of a number of conventional means that includes, but is not limited to, a key, a cipher, or a touchpad.
  • the locking mechanism can be integrally attached to the trigger guard so that the two are linked together to form one assembly; or, the lock mechanism and the trigger guard can be formed or molded as one piece with associated attached elements (i.e., the the springs, cylinder (if used), or lock shaft of the locking assembly).
  • the lock mechanism and the trigger guard are independently slidably mounted on the firearm frame and each can be separately slid along the frame or exterior surface as desired by the firearm user.
  • the engagement of the locking means further comprises the initiation of the locking mechanism engagement by accessing the lock with a key, a cipher, or a touchpad within the lock mechanism and which causes the lock mechanism to engage a lock plate integrally mounted on the frame or under the barrel if the barrel is a separate assembly from the frame, or as an exterior portion of the firearm generally; and, securing the locking mechanism to the lock plate until the mechanism is unlocked and slid rearward along the mounting track.
  • a trigger guard is slidably mounted in a firearm (can be a revolver, semi-automatic or automatic firearm) frame, thus allowing the trigger guard to slide from a home position to a locking position.
  • the trigger guard is slidably mounted on a frame or exterior portion of the firearm such that when the trigger guard is in a rearward position, then a trigger mounted in the frame can be pulled back to cause the firearm to fire; and, when the trigger guard is in a forward position, the trigger cannot be pulled back and the firearm cannot be fired.
  • a locking mechanism is mounted on the frame or exterior portion of the firearm such that when the trigger guard is in the rearward position then the trigger guard is not engaged by the locking mechanism and when the trigger guard is in the forward position then the trigger guard is engaged by the locking mechanism.
  • By sliding the trigger guard forward the trigger guard is coupled with the locking mechanism and the trigger guard is locked in place.
  • the engagement of the locking mechanism is accomplished by accessing the mechamsm through the use of a key, cipher, or touchpad within the locking mechanism which causes the locking mechanism to engage the trigger guard.
  • the lock mechanism is secured to the trigger guard until the mechanism is unlocked and slid rearward along the mounting.

Abstract

L'invention concerne un procédé et un système pour sûreté d'armes à feu. Selon l'invention, un pontet est monté de manière coulissante dans la carcasse de l'arme à feu, ce qui permet de faire glisser le pontet d'une position initiale à une position de verrouillage. Un mécanisme de verrouillage est monté sur l'extrémité avant du pontet, de sorte que lors du glissement du pontet vers l'avant, le mécanisme de verrouillage est amené à une position de verrouillage de manière à empêcher le pontet de glisser vers l'arrière. Lorsque le pontet est en position initiale ou arrière, une détente montée dans la carcasse peut être ramenée en l'arrière pour déclencher le tir de l'arme. Cependant, lorsque le pontet est en position de verrouillage ou en position avant, la détente ne peut pas être ramenée en arrière, ce qui empêche de déclencher le tir. Le blocage du moyen de verrouillage commence par blocage de la platine solidarisée à la carcasse ou à la partie extérieure de l'arme. Le mécanisme de verrouillage est fixé à la platine jusqu'à ce que le mécanisme soit déverrouillé et glissé vers l'arrière le long de la glissière de montage. Dans un autre mode de réalisation, le mécanisme de verrouillage est monté sur la carcasse ou sur la partie extérieure de l'arme à feu de sorte que lors du glissement du pontet vers l'avant, ce-dernier est couplé avec le mécanisme de verrouillage et verrouillé en place. Un sous-ensemble ressort monté dans le mécanisme de verrouillage permet de libérer le pontet lorsque le mécanisme de verrouillage est déverrouillé.
