Safe lock mechanism

A safe mechanism for use with a safe which includes a lock mechanism, a safe door, a safe door frame and a slider with one or more attached locking pins, which comprises:

• a crank shaft for opening said safe door, which penetrates said safe door and which is attached to a handle, and which includes a shoulder which when mounted to said safe door, presses against said safe door, so that an external pressure on said crank shaft is transferred to said safe door;
• a link arm with a body and a first and a second end, in which said link arm body defines a slot, with said second end of said link arm attached to said slider with one or more attached locking pins, for moving said slider with one or more attached locking pins into engagement with said safe door frame;
• a crank assembly, which comprises said crank shaft, a crank plate attached to said crank shaft, with a crank slider pin attached to said crank plate, in which said crank slider pin engages said slot in said link arm, in which said crank assembly is engageable with said lock mechanism, and in which rotation of said crank assembly about said crank shaft moves said link arm in a first direction or a second direction, by movement of said crank slider pin in said slot, and in which said crank plate comprises a first notch which is engageable with a tongue of said lock mechanism in a locked position and when said tongue of said lock mechanism is in an extended position, and in which said crank plate further comprises a second notch which is engageable with a re-locker;
• and
• an open position lock which engages said second notch, and which prevents said one or more attached locking pins attached to said slider from extending while said safe door is in an open position.

A safe mechanism for use with a safe which includes a lock mechanism, a safe door, a safe door frame, and a slider with one or more attached locking pins, which comprises:

• a link arm with a body and a first and a second end, in which said link arm body defines an L shaped slot, with said L shaped slot comprised of a horizontal portion, and a vertical portion, with said horizontal portion joined to said vertical portion at a generally ninety degree angle, and with said second end of said link arm attached to said slider with said one or more attached locking pins, for moving said slider with said one or more attached locking pins into and out of engagement with said safe door frame;
• a crank assembly, which comprises a crank shaft, a crank shoulder, a crank plate attached to said crank shaft, with a crank slider pin attached to said crank plate, in which said crank slider pin engages said L shaped slot in said link arm, in which said crank assembly is engageable with said lock mechanism, in which said crank shaft and crank slider pin extend into said horizontal portion of said L shaped slot and in which rotation of said crank assembly about said crank shaft moves said link arm in a first direction or a second direction, by movement of said crank slider pin and said crank shaft in said L shaped slot, and in which said crank shoulder is configured to transfer external pressure such as from pounding, to said safe door and not to other safe components,
• and in which rotation of said crank assembly about said crank shaft moves said link arm in a first direction to an open position or in a second direction to a closed position, by movement of said crank slider pin and said crank shaft in said L shaped slot, and wherein in said closed position lateral motion of said link arm in a first direction without simultaneous turning of said crank assembly in a first direction is blocked by said crank slider pin in said L shaped slot.
