Abstract: An improved kingpin locking system includes a kingpin lock body having upper and lower sections, the lower and upper section each having a truncated generally pyramidal shape, with the lower one being inverted, a central kingpin-receiving chamber formed in the kingpin lock body, a kingpin engagement bar movably mounted in the kingpin lock body adjacent the kingpin-receiving chamber which releasably engages the kingpin when positioned within the chamber, and a kingpin engagement bar locking device which releasably locks the kingpin engagement bar in the engagement position thereby releasably securing the kingpin lock body on a kingpin to prevent unauthorized engagement of the kingpin and thereby preventing unauthorized use of the trailer.

Abstract: An improved securement system for the doors of vehicles includes a first lock body having at least one bore hole and a second lock body having at least one bore hole, the first lock body mounted on a first door, the second lock body mounted on a second adjacent door. The first and second lock bodies are aligned such that upon the first and second doors being closed, the bore holes of each are generally concentrically aligned. A locking mechanism is mounted on the second lock body and a locking device including a pin securement block and a locking pin extends through the aligned bore holes with the pin securement block aligning with and engaging the locking mechanism to releasably secure the locking pin in the aligned bore holes thereby securing the first lock body to the second lock body to secure the doors in closed position.

Abstract: The SLIKLOC—Kingpin Lock is an anti-theft device used to prevent the theft of semi trailers that are unhooked from the semi tractor. The Kingpin Lock is virtually indestructible from ramming the semi tractor fifth wheel plate into the trailer Kingpin if attempted. The lock is designed to jump over the fifth wheel and lodge in front of the fifth wheel making movement of the tractor virtually impossible. The tractor's wheels will hit the semi dollies making any turns impossible. In addition, the ? inch, 45 degree slant (FIG. 2) will have a tendency to catch on the front of the fifth wheel making raising the trailer to free the semi tractor fifth wheel from the trailer very difficult.

Abstract: The SLIKLOC Security System Permanent Locking Hasp has the highest level of anti-theft and anti-tampering design that virtually eliminates opening with a thief's tools of the trade—hacksaws, bolt cutters, large hammers, and pry bars. Most marine and railroad intermodal containers are unsecured or have limited security. Adding the SLIKLOC Security System to these modes of transportation would limit theft and decrease the chance of terrorists using these modes of transportation to damage our homeland.
