Magnetic shield for a solenoid operated locking device
First Claim
1. A locking device, for securing an object within the locking device, said locking device comprising:
- a first portion and a second portion;
at least one of said first portion and said second portion configured, in one mode, for movement with respect to the other of said first and second portions and in another mode, for being held in a fixed and locked position vis-à
-vis each other;
at least one of said first portion and said second portions including an electro-mechanical locking mechanism, said at least one of said first portion and said second portion including said electro-mechanical locking mechanism constructed of a non-magnetically conductive material, said electro-mechanical locking mechanism including a solenoid and spring loaded pin, said spring loaded pin responsive to activation and deactivation of said solenoid to cause said spring loaded pin to be operable between a first position and a second position, wherein in a first position, said spring loaded pin is configured for preventing said first portion and said second portion from moving with respect to the other of said first portion and said second portion, and wherein in a second position, said spring loaded pin is configured for allowing said first portion and said second portion to move with respect to the other of said first portion and said second portion, said solenoid of said electro-mechanical locking mechanism responsive to at least one of an electrical activation and activation from an external magnetic field of sufficient magnitude, to cause said spring loaded pin to be operable between said first position and said second position; and
a magnetically conductive shield, disposed proximate said electro-mechanical device including the solenoid, and configured for shielding said external magnetic field of sufficient magnitude from activating said solenoid and spring loaded pin and operatively causing said spring loaded pin mechanism of said locking mechanism to move from said first position to a second position by sufficiently disbursing any magnetic forces from the external magnetic field of a magnet or other external magnetic field producing device away from the electro-mechanical device.

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.
