Abstract

Abstract Door-fastening apparatus, particularly well suited for fastening in closed position the rear doors of truck bodies, comprises a shaft and its actuating means mounted on the door, a keeper lock member mounted on the door frame, and a latch lock member, actuatable by rotation of the shaft, mounted on the door. The keeper member has two spaced projecting members of which one has a stem portion and a transverse portion, and the other of which has a free end portion. The latch member has two forks one of which engages beneath the transverse portion of the first projecting member in straddling relation and the other of which straddles the second projecting portion. The door also carries a member having an extension portion that overlaps the door frame to prevent inward movement of the door. This member preferably extends around the keeper member and is engaged by the forked portion of the latch member when the latch member is in locking engagement.
