ABSTRACT:
A tamper evident, cargo container door lock structured to be used on a cargo container of the type having a pair of doors secured in a closed orientation by a closure assembly of the type including a lock rod and an actuation handle connected to the lock rod to facilitate pivotal movement of the lock rod and permit slided movement thereof to release the door from the closed orientation, the door lock including a primary shroud assembly formed of a substantially strong, cut resistant metal and structured to cover and shield from external access a connection joint between the actuation handle and the lock rod of the closure assembly, thereby preventing access to the connection joint without cutting or removing the primary shroud assembly. Further, the door lock includes a pivot brace which securely engages the primary shroud assembly and prevent pivotal movement thereof about an axis of the lock rod, thereby preventing pivotal movement of the actuation handle and the connection joint of the closure assembly which are encased by the primary shroud assembly. Both the pivot brace and the primary shroud assembly are covered by a tamper evident coating which is substantially difficult to un-noticeably repair upon the primary shroud assembly or the pivot brace, and accordingly the tamper evident coating, being cut, thereby providing a clear, positive indication of tampering with the door lock.
