ABSTRACT:
The locking apparatus on a flatbed vehicle, etc., for engaging the corner fitting on a container carried thereby includes a shank with a crosshead which is moved into the corner fitting and is rotated 90.degree. to engage the locking device. The shank has an annular rack thereon. A gear segment engages this rack and is rotated manually to push the rack one way or the other to establish the desired axial position of the shank. On the distal end of the shank is a gear which engages a gear on a rotatable locking member. The locking member has teeth which engage the teeth of the rack to prevent axial movement of the rack and shank when the crosshead on the shank is in the locked position in the container corner fitting. The locking member is rotatable to move its teeth away from the rack and that rotation correspondingly rotates the shank. Ultimately that rotation results in the crosshead on the shank being aligned with the opening in the container corner fitting, whereupon the shank can be moved axially to commence the withdrawal of the crosshead from the corner fitting.
