Abstract:
1. A safe or security door comprising: a locking mechanism with an extendable and retractable tongue; a locking pin connected to a locking pin connection plate; a force transfer plate with an opening to receive the tongue from the locking mechanism, said force transfer plate further having a slot; a rotational entry shaft connected to a single bar force transfer actuator with a single force transfer shaft, wherein said entry shaft, actuator and transfer shaft are positioned relative to said transfer plate such that said force transfer shaft is located in said slot and wherein rotation of said entry shaft extends or retracts said locking pins by way of movement of said locking pin connection plate and said force transfer plate; wherein in the door locked status said force transfer shaft is positioned in contact or near contact with said slot, and further wherein said locking pin and force transfer plate are restrained in the closed position by the contact or near contact of said force transfer shaft in said slot, further wherein said force transfer shaft is restrained in position by said transfer actuator and said rotational entry shaft; and wherein said slot is aligned substantially perpendicular to the direction of locking pin travel, and further wherein said slot is aligned in a direction such that under conditions of a force applied to said locking pin in the direction of pin retraction, the position of said force transfer shaft within said slot is restrained in the closed position.
