ABSTRACT:
A door lock, such as would be used on truck bodies to securely fasten the big rear doors, or which is easily opened to remove merchandise stored in the truck. A locking rod runs vertically the length of the door, with a pivotable handle attached at a reachable height from the bottom, the handle being raised to clear the lock, and then rotated a quarter to half revolution, to thereby rotate the locking rod and free it from hasps at top and bottom of the rod. A spur extends out from the handle and has a series of stepped shoulders which progressively enter the lock to secure the handle against movement when desired.
