ABSTRACT:
This invention relates to equipment for securing a truck trailer against theft by protecting the trailer kingpin against being secured by a tractor. The device employs a lock housing or body which has a hole which is adapted to fit over the trailer kingpin. A sliding member is employed to go into sliding contact with the groove in a standard trailer kingpin. The sliding member is configured with a concave edge on one end in order to contact the annular groove in the standard trailer kingpin. A slot in the sliding member is used to engage the body of a heavy duty padlock when in the locked position thus holding the sliding member in contact with the trailer kingpin. A retaining means such as a screw threadably secured to the lock body and a mating slot in said sliding member is employed to prevent the inadvertant removal of said sliding member from the lock body.
