Abstract
The invention is a cam locking rod devices for securing doors on intermodal cargo containers, semi-trailers, utility trailers, trucks, and other similar cargo storage compartments. The lock rod device is used in conjunction with a rotatable cam lock rod, having cam locks on each end, mounted on a container door for securing the container door in a locked condition. A locking cylinder, through which the cam lock rod extends, has at least one locking projection thereon which interacts with at least one projection on a sliding latch, which when intermeshed prevents rotation of the cam lock rod. A pad lock is used in conjunction with the sliding latch to lock projections on the locking cylinder and slide latch in a meshed position which prevents rotation of the cam lock rod.

A cam locking rod device for securing doors on intermodal cargo containers, semi-trailers, utility trailers, trucks, and other similar cargo storage compartments, comprising:
- a rotatable cam lock rod, having cam locks on each end, adapted to be mounted on a container door;
- a locking cylinder, through which the cam lock rod extends, having at least one locking projection thereon;
- a sliding latch having at least one projection thereon for interacting with the at least one projection on the locking cylinder;
- a lock having a shoulder adjacent to and in movable contact with the sliding latch;
- a spring in contact with the sliding latch biasing the sliding latch in a position in which the at least one projection thereon is in a non-meshed relation to the at least one projection on the locking cylinder;
- whereby, when the lock is placed in a locked condition, the lock moves the sliding latch against the bias of said spring, and the projections thereon into a locked position with the projections on the locking cylinder preventing rotation of the cam lock rod.
