ABSTRACT:
A locking arrangement for a bulkhead door in a freight transport vehicle in which locking plates are selectively positioned along tracks on each side of the vehicle floor, and are engaged by locking pins in the bulkhead door. A locking track is mounted in the transport vehicle floor along each side thereof, and extends along a substantial portion of the length of the vehicle. Each track consists of an elongated, rectangularly-shaped steel plate positioned to extend along a longitudinal side of the vehicle, and has a number of vertically-extending holes formed therein and spaced along its length. Each locking plate has a relatively short length in comparison to a locking track, and has several posts extending vertically downwardly from its bottom to engage the holes in a locking track. Each locking plate has a number of vertically-extending holes spaced along its length, with the number of holes per unit length in each plate being substantially greater than the number of holes per unit length in each locking track. The arrangement allows a locking plate to be selectively positioned along the length of a locking track at a location where a bulkhead door is to be placed. The bulkhead door is then vertically positioned in the vehicle, and vertically extensible pins on each side of the bulkhead door engage one of the holes in the locking plates on each side of the transport vehicle.
