ABSTRACT:
A lock box for preventing unauthorized use of electrical appliances is disclosed. The lock box is adapted to receive the plug end of an electrical cord to prevent the appliance from being plugged into an electrical socket. The lock box includes a drawered cabinet arrangement wherein the drawer has a slot sized and shaped such that the electrical cord, but not the plug itself, may freely pass therethrough. A locking mechanism is provided to facilitate locking the drawer with the plug closed inside, thereby preventing unauthorized use. The lock box does not contain any electrical parts and therefor may be safely used in virtually any environment. A method of preventing the unauthorized use of electrical appliances is also disclosed.
