![]() The rotatable lock pin embodiments described herein can be employed as abutments against the door frame or other components of a safe body to prevent or inhibit opening of the door. In accordance with embodiments of the subject invention, the ability to forcibly breach an opening or door is inhibited by the use of lock pins that can be rotated, so as to directly couple or conjoin to one or more components of the safe body. If the hand wheel is turned in the opposite direction, the carriage is moved away from the door panel frame, retracting the lock pins through the pin holes, so they cannot abut the door frame, allowing the door to be opened. Thus, they can abut or otherwise engage with the door frame in the safe body to lock the door in place. They typically operate by a lever system controlled with the hand wheel that is turned in one direction to move the carriage towards the edge of the door so that the lock pins are extended through pin holes in sides of the door panel frame. There is a multitude of locking systems utilized with safes that include and are operated with a hand wheel or lever to move the carriages and the lock pins attached thereto. Larger or commercial grade safes may have heavier carriages, more lock pins, or both but, the principle of operation is often the same. The locking system is usually attached to and controls the movement of carriages, which have a series of cylindrical lock pins attached thereto, positioned along the interior sides and sometimes the top and bottom of the door. Most types of safes, including commercial safes and larger home safes, have a hand wheel or lever on the exterior side of the door that is attached through an opening in the door to a locking system on the interior side of the door.
