MAGNETIC SHIELD FOR A SOLENOID OPERATED LOCKING DEVICE

摘要

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.

主权项

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.
