Safe locking mechanisms and related apparatus

A lockable structure, comprising:

• a body;
• a door coupled with the body and configured to enclose the body when the door is in a closed position, wherein the door comprises an outer periphery defined in between upper and lower portions of the door and opposing sides of the door;
• at least one locking member coupled with the body;
• an actuation member moveably coupled with the door;
• and
• at least one engagement member coupled with the actuation member, wherein, upon actuation of the actuation member with the door in the closed position, the at least one engagement member is configured to selectively engage the at least one locking member to prevent the door from being opened, wherein the at least one engagement member is configured to move between a first position and a second position during a locking actuation, wherein the second position is closer to the outer periphery of the door than the first position, and wherein at least a portion of the at least one engagement member that engages the at least one locking member is configured to avoid extending beyond a perimeter of the door.

A locking mechanism, comprising:

• a door;
• an actuator accessible from an outer surface of the door;
• an actuation member coupled with the door and configured to translate towards a perimeter of the door in response to actuation of the actuator;
• a protruding locking member fixedly mounted to a structure adjacent to the door;
• and
• an engagement member coupled with the actuation member, wherein the engagement member is configured to selectively engage the protruding locking member upon actuation of the actuator with the door in a closed position to lock the door in the closed position.
