Abstract: A magnetic shield for a locking device such as a gunlock having a first portion and a second portion configured for controlled movement with respect to the other portion and for being held in a fixed and locked position vis-à-vis each other. At least one of the first and second portions includes an electromechanical locking mechanism including a solenoid and solenoid activated spring loaded pin configured, in a first position, for preventing the first and second portions from moving with respect one another and in a second position for allowing the first and second portions to move vis-à-vis one another. A magnetically conducive shield is disposed on or in at least one of the first and second portion that includes the solenoid locking mechanism, for preventing an unauthorized magnetic field from causing the solenoid to retract the spring loaded pin thereby allowing the locking device to be opened.

Abstract: An apparatus for adapting a clamshell-type of gunlock for a shotgun to lock a rifle. The clamshell gunlock can be easily modified using the apparatus without the need for basic changes to the gunlock. The apparatus has a single molded rubber part attached to the gunlock to hold the buffer tube of a rifle; providing a snug fitting constraint to hold the buffer tube of the rifle such that the rifle will not vibrate or move causing rattling sounds or damage to the rifle.

Abstract: An apparatus for adapting a clamshell-type of gunlock for a shotgun to lock a rifle. The clamshell gunlock can be easily modified using the apparatus without the need for basic changes to the gunlock. The apparatus has two parts: a first insert, attached to the base of the gunlock to reduce the volume of the gunlock to hold a rifle; and a second insert, frictionally attached to said first insert to provide a snuggly fitting constraint to hold a portion of the rifle such that the rifle will not vibrate or move causing rattling sounds or damage to the barrel.

Abstract: A security apparatus to prevent unauthorized opening of a ratchet type gunlock. A hook is permanently anchored to the housing of the lock and a groove is provided in the rotatable ratchet arm. When the hook is within the groove this forms, in essence, a closed loop so that the only way to force open the ratchet arm is to break the lock by breaking the hook or the arm even if the gunlock is attempted to be opened by severe force.

Abstract: A security apparatus for a ratchet type gunlock that has a ratchet for locking the gunlock. The security apparatus prevents the gunlock from being shimmed using shimming techniques well known in the art. A star-shaped cogwheel having asymmetrical teeth prevents the shim from reaching the locked ratchet. The security apparatus also provides an extended ratchet latching assembly that features a pivot and a unique shoe-shaped latch that attaches to a plunger via a ball head such that the connections provided between the three elements of the latching assembly enable the latching assembly to remain locked despite severe impact, wrenching or shaking, yet can be easily opened even once the forces being applied to the gunlock ceases even when the deformation to the gunlock is irreversible.
