Abstract
A kingpin security device is provided preferably having a semi-circular plate transverse to a flat base. The plate has a channel therein, also preferably being semi-circular in cross-section. The channel in the plate defines a shoulder thereabove. The dimensions of the channel and the shoulder are such as to form a close fit with the annular recess and annular lip found on a standard kingpin. Opposite the vertically extending plate, the base transitions to a longitudinally extending arm. At the distal end of the arm is a shield plate, disposed generally transverse and spaced apart from the base. After the kingpin security device is affixed to a kingpin, a standard padlock can be attached to this extending arm. The shackle of the padlock prevents disengagement of the kingpin from the kingpin security device. The shield plate prevents the padlock from slipping off the arm, as well as shielding it from vandals or intruders. The kingpin security device also includes a downwardly extending vertical flange. This flange also serves to protect the body and shackles of the padlock.
