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.

Claims

1. A clamshell style gunlock having a magnetic shield comprising:

a first portion, said first portion including a first hinge component;

a body portion including a second hinge component configured for cooperatively engaging with the first hinge component of said first portion, for allowing at least said first portion to move pivotably with respect to said body portion;

at least one of said first portion and said body portion including a locking mechanism, said locking mechanism including a spring loaded pin mechanism configured, in a first position, for preventing said first portion or said body portion from moving pivotably with respect to the other of said first portion and said body portion;

an electro-mechanical device, configured for operatively causing said spring loaded pin mechanism to move from said first position to a second position, wherein said second position allows one of said first portion or said body portion to move pivotably with respect to the other of said first portion and said body portion; and

a magnetically conducive shield, disposed proximate said electro-mechanical device , and configured for shielding an externally provided magnetic field from acting on and activating said electro-mechanical device.

2. The gunlock of claim 1, wherein said magnetically conductive shield is disposed along an external portion of at least one of the first portion and the body portion.

3. The gunlock of claim 2, wherein said externally disposed magnetically conductive shield is added to said gunlock after construction and manufacturing of said gunlock.

4. The gunlock of claim 2, wherein said externally disposed magnetically conductive shield is added to said gunlock during construction and manufacturing of said gunlock.

5. The gunlock of claim 1 wherein the electro-mechanical device further comprises a solenoid disposed in said body portion, and a locking pin, coupled to said solenoid, said locking pin configured in a first extended position for aligning with a counterpart recess within the first portion when the first portion is in a closed position abutting said body portion;

and

wherein said solenoid is configured to operate in an energized state and a non-energized state, and wherein in an energized state, the solenoid is configured to retract the lock pin out of the recess within the first portion.

6. The gunlock of claim 1, wherein said magnetically conductive shield is disposed in an internal portion of at least one of the first portion and the body portion.

7. 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 electro-mechanical locking mechanism including a solenoid and spring loaded pin, said spring loaded pin 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; and

a magnetically conducive shield, disposed proximate said electro-mechanical device including the solenoid, and configured for shielding external magnetic fields from activating said solenoid and spring loaded pin to move into said second position.

8. The locking device of claim 7, wherein said locking device includes a gunlock for securing a weapon.

9. The locking device of claim 7, wherein said magnetically conductive shield is disposed along an external portion of at least one of the first portion and the second portion.

10. The locking device of claim 9, wherein said externally disposed magnetically conductive shield is added to said locking device after construction and manufacturing of said locking device.

11. The locking device of claim 9, wherein said externally disposed magnetically conductive shield is added to said locking device during construction and manufacturing of said locking device.

12. The locking device of claim 9, wherein said magnetically conductive shield is disposed in an internal portion of at least one of the first portion and the second portion.
