Roll-up door lock

In combination:

• a van body having a floor and a vertically movable roll-up door adapted to be lowered into engagement with the floor to close an opening in the van body, said floor having a recess formed therein extending downwardly thereinto and a longitudinally extending pin means positioned within said recess;
• a locking handle pivotally secured, about a horizontal axis, to said door adjacent the exterior lower edge thereof, said handle being pivotally movable between first and second positions;
• said locking handle having an arcuate hook member associated therewith for pivotal movement with said handle, said hook member being positioned beneath said pin means when said handle is in its first position, to prevent the raising of said roll-up door, said hook member being pivoted out from under said pin means when said handle is in its second position, to allow the raising of said roll-up door;
• and
• a selectively actuated lock means secured to the exterior surface of said door laterally of said locking handle and including a horizontally movable dead bolt operable between locked and unlocked conditions, said dead bolt being immovably locked in the pivotal path of said arcuate hook member when in its locked condition to prevent the movement of said locking handle to its second position, and said dead bolt being horizontally movable by contact from said arcuate hook member when in its unlocked condition to allow movement of said locking handle to its second position.
