License plate security lock
US Pat. App 12658141 – Filed Feb 3, 2010
A license plate security device comprises a slip collar into which a license plate mounting machine screw is inserted. These are inserted into a spin barrel assembly with a closed bottom and an open top. The license plate is installed on the vehicle using at least one of these license plate security devices, more machine screws, and an ordinary screwdriver. A cabinet style key lock is inserted into the open end of the spin barrel and covers the head of the machine screw. A weather cap is snapped over the lock and spin barrel to keep out dirt, water, and ice. Removing the license plate now requires a key to remove the lock from the spin barrel to access the head of the machine screw. Turning the spin barrel only will not remove the machine screw because the collar creates a slip joint and will not transmit enough torque.
