ABSTRACT:
A kingpin coupler for allowing a user to connect a trailer having a kingpin to a towing vehicle. The kingpin coupler includes a head assembly, casting, jaws and a locking slide bar. The jaws are pivotably mounted in the housing and are biased into the open position by springs. When the jaws are in the open position and the locking slide bar is unlocked, the jaws prevent the locking slide bar from moving to the closed position. When the hitch ball is moved between the jaws, the jaws move to the closed position and, the unlocked, locking slide bar automatically moves to the closed position across the front of the jaws when the jaws are in the closed position.
