ABSTRACT:
A locking device is described particularly useful for coupling a container to a crane, the locking device including a lock-pin assembly coupleable to the crane, and a slotted member fixed to the container into which member the lock-pin assembly may be inserted and then locked.
The slotted member is formed with an oval slot and a square cavity underlying and communicating with the slot and having a length and width at least equal to the length of the slot. The lock-pin assembly comprises a pin, an axial-stop element fixed to the inner end of the pin, and a rotary-stop element fixed to the inner end of the pin between the axial-stop element and the outer end of the pin. The lock-pin assembly further includes a handle at the outer end of the pin which handle enables the user to insert both stop elements of the pin assembly through the slot and into the cavity, to turn the assembly one-quarter turn, and to pull the assembly partially out of the slot until the axial-stop element engages the wall of the cavity and the rotary-stop element engages the walls of the slot.
