Abstract
A robber trapping door has a locking assembly comes into function in order to lock the trapping door, it is comprised of a locking bar that extends so as to interfere with a triangular member, which locks the door from turning in one direction. To prevent the door from turning in the opposite direction, a pair of ratcheting means normally operate so as to also interfere with the triangular member. The ratcheting means work in a fashion similar to ratchets of the prior art, meaning that they will be movable when pushed in one particular direction but unmovable when pushed in any other directions by way of a biasing means, which brings them back to their original position.
