Anti-intrusion door security device

Abstract

Abstract A DEVICE WHICH MAY BE ATTACHED TO EXISTING DOORS OF A RESIDENCE TO SAFEGUARD AGAINST UNWARRANTED INTRUSION WHILE THE OCCUPANTS ARE SLEEPING OR WHEN ANSWERING A KNOCK AT THE DOOR, I.E., THE DEVICE MUST BE ACTUATED BY A PERSON WITHIN THE RESIDENCE. THE DEVCE INCLUDES A SUBSTANTIALLY INDESTRUCTIBLE TEMPERED STEEL BAR WHICH BRIDGES THE CRACK OF A DOOR THAT IS AJAR. THE BAR IS SUSPENDED FROM A PAIR OF SHORT CHAINS WHICH ARE INACCESSIBLE FROM THE EXTERIOR SIDE OF THE DOOR. THE FREE END OF ONE OF THE CHAINS IS ATTACHED TO A WEDGE WHICH IS REMOVABLY RECEIVED BY A PECULIAR TAMPERPROOF RECEPTACLE. THE RECEPTACLE IS ATTACHED TO A WRAPAROUND PLATE THAT IS SUITABLY FITTED TO THE DOOR PANEL BY UTILIZING THE EXISTING DOOR KNOB HARDWARD TO AID IN THE ATTACHMENT THEREOF AND FOR MORE POSITIVE REINFORCEMENT. THE OTHER CHAIN HAS THE OPPOSITE END ATTACHED TO STRUCTURE WHICH IS ANCHORED INTO EXISTING ADJACENT STUD STRUCTURE, I.E., 2" X 4" LUMBER OR THE LIKE, SO THAT THE WALL AND/OR THE DOOR PANEL WOULD SPLINTER BEFORE THE DEVICE WOULD BECOME DISENGAGED FROM EITHER THE WALL OR THE DOOR PANEL, IRRESPECTIVE OF THE AMOUNT OF FORCE BEING EXERTED FROM WITHOUT. THE DOOR MAY BE OPENED SLIGHTLY TO GREET CALLERS OR GUESTS WHILE THE DEVICE IS ENGAGED WITH ABSOLUTE ASSURANCE THAT UNWARRANTED INTRUDERS CANNOT BREAK IN, I.E., THROUGH THE PARTIALLY OPENED DOOR.
