Door Locking Device

Abstract

A device including a doorknob, rotating disc implements, two steel connecting wires, two connecting rods, and weak-link connectors configured to disable the steel connecting wires when an excessive force is applied to the doorknob. One of the connecting rods comprises a spring loaded connecting rod configured to engage a threaded hole of a sliding bolt. The other connecting rod comprises a connecting rod configured to engage a separator pinion in the sliding bolt. The spring loaded sliding bolt enables the device to be positioned in a locked or unlocked condition. The device is configured to be installed in the center of a door to secure the door to a door frame. The door and door frame may each be made of wood or steel.

What is claimed is: 
     
         1 . A device comprising:
 a doorknob, said doorknob comprising, at least one of, an interior doorknob with a button lock and an exterior doorknob, wherein said doorknob is configured to install on a surface of a door;   a first rotating disc implement, in which said first rotating disc is coupled to said interior doorknob;   a first steel connecting wire, wherein one proximate end of said first steel connecting wire is into engagement with said first rotating disc implement, while another proximate end of said first steel connecting wire is into engagement with a first connecting rod;   wherein said first connecting rod comprises at least a spring loaded sliding bolt connecting rod configured to engage a threaded hole of a sliding bolt, wherein said first connecting rod is into engagement with the other proximate end of said first steel connecting wire;   a second rotating disc implement, wherein said second rotating disc implement is generally coupled to said exterior doorknob;   a second steel connecting wire, wherein one proximate end of said second steel connecting wire is into engagement with said second rotating disc implement, while another proximate end of said second steel connecting wire is into engagement with a second connecting rod;   wherein said second connecting rod comprises at least a separator pinion connecting rod configured to engage a separator pinion in said sliding bolt, wherein said second connecting rod is into engagement with the other end of said second steel connecting wire;   a first weak-link connector, wherein said first weak-link connector is disposed on a proximate middle portion of said first steel connecting wire, and wherein said first weak-link connector is configured to disable said first steel connecting wire when an excessive force is applied to said doorknob; and,   a second weak-link connector disposed on a proximate middle portion of said second steel connecting wire, wherein said second weak-link connector is configured to generally disable said second steel connecting wire when an excessive force is applied to said doorknob, wherein said sliding bolt is into engagement with said spring loaded sliding bolt connecting rod and said separator pinion connecting rod, wherein said sliding bolt comprising at least a spring loaded sliding bolt operable to enable said device to position in a locked or unlocked condition.   
     
     
         2 . The device of  claim 1 , wherein said doorknob is configured to install in the center of said door. 
     
     
         3 . The device of  claim 1 , wherein said device is configured to install on a surface of said door wherein said door is made of wood. 
     
     
         4 . The device of  claim 1 , wherein said device is configured to install on a surface of said door wherein said door is made of steel. 
     
     
         5 . The device of  claim 1 , wherein said device comprises means for securing said door to a door frame. 
     
     
         6 . The device of  claim 5 , wherein said device is configured to secure said door to said door frame wherein said door frame is made of wood. 
     
     
         7 . The device of  claim 5 , wherein said device is configured to secure said door to said door frame wherein said door frame is made of steel.
