Abstract:

A lock shielding assembly for preventing unauthorized access to a lock by providing a shield over the lock which can easily be removed by authorized individuals, while requiring an unauthorized person an extensive amount of time to open. The assembly includes a housing which can be superimposed over the front face of the lock. The housing includes a slot positioned between a front and rear wall and includes cooperating openings in the walls providing access to the key hole of the lock. A shield plate is slidably mounted in the slot for movement to and from a position covering the lock. A plurality of pins extend into the front wall, selectable ones of the pins extending through the front wall and into engagement with the shield plate to retain the shield plate in its position covering the lock. The location of the selected pins are known only to the authorized user who can easily remove them, while the unauthorized individual must remove all or most of the pins. A cover plate is removably superimposed and lockable on the housing to prevent access to the pins and provides a further measure of security.
