High security locking assembly for lockrods type rear-end closures of cargo vehicles

In removable combination with a cargo carrying vehicle wherein the closure therefor comprises a pair of upright lockrods having a finite lateral-spacing at closed condition, the lockrods being relatively laterally movable whereby entrance into the cargo compartment is attainable only by moving one lockrod laterally away from the other lockrod, a high security locking assembly for said cargo compartment closure and comprising:

• A. an upright primary J-hook member including a relatively long leg attached to a parallel and directionally transversely separated relatively short leg attached at a curved bight for snugly removably engaging one of said lockrods, the longer leg remote of the bight carrying an upright apertured staple extending directionally transversely toward the shorter leg;
• B. an upright secondary J-hook member including a relatively long leg attached to a parallel and directionally transversely separated relatively short leg attached at a curved bight for snugly removably engaging the other lockrod, at least one of the legs of the secondary member being provided with a plurality of regularly spaced upright slots, one of which receives therethrough the apertured staple of the primary member;
• and
• C. a padlock of the type comprising a body and a U-shaped shackle and a body, said padlock is activated condition having its shackle extending through the aperture of the staple with the member legs in substantially parallel assembled relation, whereby said padlock maintains the primary and secondary J-hook members and their engaged lockrods in arrested relationship and whereby the padlock is protectably shielded by the removably associated primary and secondary J-hook members.
