Patent ID: 6997487

Claim:
A locking arrangement comprising: a receptacle having a cover, the receptacle and cover having overlapping parts with aligned holes therein; a handle for engagement for pulling the locking arrangement from the aligned holes in a withdrawing direction, the handle being outside the receptacle and having an enlarged portion for being held by one hand of a user of the locking arrangement; an actuator mounted for movement to the handle and having a first end for being outside the receptacle and a second end for being inside the receptacle, the actuator extending through the aligned holes for locking the overlapping parts together; expansion means at the second end of the actuator for expanding to an expanded geometry having at least one dimension which is greater than a dimension of the aligned holes to prevent withdrawing the actuator from the aligned holes when the actuator is pushed in an unlocking direction that is opposite to the withdrawing direction, the expansion means having a contracted geometry which is at most equal to the dimension of the aligned holes for allowing withdrawing of the actuator from the aligned holes; biasing means engaged with the expansion means for biasing the expansion means toward the expanded geometry so that when the actuator is not being pushed, the expansion means is in the expanded geometry, the biasing means acting to bias the actuator in a releasing direction that is the same as the withdrawing direction; and release means connected to the actuator for reducing the effective diameter of an outer end of the actuator to allow the actuator to be pushed through the handle and into the receptacle so that the cover can be removed in case the locking arrangement becomes caught in the aligned holes, said release means comprising the actuator having the outer end thereof threaded and including a nut threaded on the outer threaded end of the actuator and a screwdriver slit in the outer threaded end of the actuator for holding the actuator against rotation when the nut is un-threaded from the outer threaded end to remove the nut and thereby reducing the effective diameter of the outer end of the actuator.
