Force deflector
Disclosed herein are various exemplary mechanisms by which external forces applied to doors and their locking mechanisms are deflected or directed away from the critical components of the locking system thereby preserving the integrity of the locking system and preventing unauthorized entry. Detailed information on various example embodiments of the inventions are provided in the Detailed Description below, and the inventions are defined by the appended claims.

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.
2. A safe or security door according to claim 1 , further comprising: multiple locking pins connected to the locking pin connection plate.
3. A safe or security door according to claim 1 , further comprising: wherein said single bar force transfer actuator is connected to multiple force transfer shafts.
4. A safe or security door according to claim 1 , wherein said force transfer plate opening is configured to provide a sufficient distance between said transfer plate and said tongue in the locked position that a force applied to said locking pin in the direction of pin retraction is transferred to any of said plate, actuator or shaft and not to said tongue.
5. A safe or security door according to claim 1 , wherein said force transfer plate opening is configured to provide a sufficient distance between said transfer plate and said tongue in the locked position that a force applied to said locking pin in the direction of pin retraction is transferred to any of said plate, actuator or shaft before failure of said locking mechanism or said tongue, allowing for some deflection or movement of said locking mechanism and said tongue.
6. A safe or security door comprising:
a door frame;
a lock with an extendable and retractable locking bar;
latches connected to a latch plate;
a force transfer bar connected to the latch plate, with the force transfer bar having an opening to receive the locking bar, said force transfer bar further having a slot;
a rotational entry pin connected to a single bar force transfer rod with a single force transfer pin, wherein said entry pin, rod and transfer pin are positioned relative to said transfer bar such that said force transfer pin is located in said slot and wherein rotation of said entry pin extends or retracts said latches by way of movement of said latch plate and said force transfer bar;
wherein when in locked status the latches engage the door frame and the locking bar engages the force transfer bar thereby preventing the door from being opened;
wherein in the locked status said force transfer pin is positioned in contact or near contact with said slot, and further wherein said latches and force transfer bar are restrained in the closed position by the contact or near contact of said force transfer pin in said slot, further wherein said force transfer pin is restrained in position by said transfer rod and said rotational entry pin; and
wherein said slot is aligned substantially perpendicular to the direction of latch travel, further wherein said slot is aligned in a direction such that under conditions of a force applied to any of said latches in the direction of retraction, the position of said force transfer shaft within said slot is restrained in the closed position.
7. A safe or security door according to claim 6 , wherein said force transfer bar opening is configured to provide a sufficient distance between said transfer bar and said locking bar in the locked position that a force applied to any one of said latches in the direction of retraction is transferred to any of said transfer bar, force transfer pin or rotational entry pin and not to said locking bar.
8. A safe or security door according to claim 6 , wherein said force transfer bar opening is configured to provide a sufficient distance between said transfer bar and said locking bar in the locked position that a force applied to any one of said latches in the direction of retraction is transferred to any of said transfer bar, force transfer pin or rotational entry pin before failure of said lock or said locking bar, allowing for some deflection or movement of said lock and said locking bar.
9. 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;
wherein said slot is aligned substantially perpendicular to the direction of locking pin travel, 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; and
wherein a force less than the force required to cause failure of said locking mechanism reaches said tongue under the conditions of (1) said door is in locked status and (2) a force is applied to any one of said locking pins in the direction of pin retraction, that force being less than that required to cause failure of any of said force transfer plate, said rotational entry shaft and said actuator.
10. A safe or security door according to claim 9 , wherein said force transfer plate opening is configured to provide a sufficient distance between said transfer plate and said tongue in the locked position that a force applied to said locking pin in the direction of pin retraction is transferred to any of said plate, actuator or shaft and not to said tongue.
11.
