Abstract
The invention relates to a safe mechanism for resistance to drilling, by use of a door mounted crankshaft mechanism. The crankshaft includes a shoulder which transfers force to the safe door rather than transmitting it to other lock mechanism components. A crank plate attached to the crankshaft rotates from an open position to a locking position, and by rotation moves a link arm with attached locking pins laterally into engagement with the doorframe. A re-locker device locks both the crank plate and the link arm in place to make entry more difficult.
