摘要： A device for controlling access to a firearm having a muzzle with a muzzle device. The device includes a lock housing with a cavity to receive the muzzle device. The device also includes a lock mechanism shaft coupled to a lock mechanism that is configured for rotational movement upon actuation of the lock mechanism. The lock mechanism shaft is coupled to a cam that moves axially upon rotation of the lock mechanism shaft. A bidirectional rotatable shaft is coupled to the cam and is insertable into the muzzle of the firearm. The device also includes a plurality of arms coupled to a perimeter of the cam and arranged for pivotal and radial movement to secure the firearm muzzle in the cavity of the lock housing. A plurality of tabs are arranged on the arms for engagement with the muzzle device to retain the muzzle device within the lock housing.

摘要： A device for controlling access to a firearm having a muzzle with a muzzle device. The device includes a lock housing with a cavity to receive the muzzle device and a portion of the barrel. The device also includes a lock mechanism shaft coupled to a lock mechanism that is configured for rotational movement upon actuation of the lock mechanism. The lock mechanism shaft is coupled to a cam that moves axially upon rotation of the lock mechanism shaft. A bidirectional rotatable shaft is coupled to the cam and is insertable into the muzzle of the firearm occupying the full length of the firearm's muzzle device, barrel and chamber. The device also includes a plurality of arms coupled to a perimeter of the cam and arranged for pivotal and radial movement to secure the firearm muzzle in the cavity of the lock housing. A plurality of tabs are arranged on the arms for engagement with the muzzle device to retain the muzzle device within the lock housing.

摘要： A device for controlling access to a firearm having a muzzle. The device includes a shaft that may be rigid or flexible and a slotted cylinder arranged for retaining the shaft thereto. The cylinder may also be flexible in an embodiment of the invention. The device includes a plurality of components that cooperatively ensure that any form of tampering is resisted so that the firearm remains secure. The device includes a lock housing and a lock foundation, wherein the lock housing is arranged to receive a key. The cylinder and shaft are removably attachable to the lock foundation. The cylinder-shaft combination is arranged for insertion into the muzzle. A gear engaged with the shaft causes movement of the shaft into the cylinder. A collet includes one or more radially displaceable tabs arranged for insertion in slots of the cylinder when the shaft moves through the collet into the cylinder.

摘要： A device for controlling access to a firearm having a barrel with various physical features proximal thereto, including a muzzle device. The device includes a lock housing with a cavity to receive the barrel. The device also includes a lock mechanism shaft coupled to a lock mechanism that is configured for rotational movement upon actuation of the lock mechanism. The lock mechanism shaft is coupled to a cam that moves axially upon rotation of the lock mechanism shaft. A bidirectional rotatable shaft is coupled to the cam and is insertable into the barrel of the firearm. Embodiments described include variants on the use of a plurality of tabs such as arm, tab, and/or housing configurations to receive and grasp the muzzle device, firearm fixed front sights, bead front sights and/or accessories such as, for example, Picatinny rails, vertical or near vertical serrations, cuts and/or grooves located on the distal lateral and ventral regions of the frame and/or slide.

摘要： A firearm-securing device providing tamper resistance features which device includes a keyway that operates a threaded rod which, in turn, controls spring-loaded cams that obstruct a tubular area including a chamber, a barrel, and a muzzle of a firearm. The cams have either fixed or articulated contact pads. Operating the keyway in clockwise rotation causes the cams to wedge against the inner chamber and barrel surfaces, locking the device in place. Counterclockwise keyway rotation unseats the cams, allowing the device to be remove from the chamber and barrel and thus allow operation of the firearm. The device includes several components designed to minimize tampering of the device itself as well as tampering of the firearm.
