Abstract

There is provided a door frame security device, the frame having an inside portion and an outside portion with a strike plate affixed thereto, the strike plate mating with a bolt of the door as the bolt passes through it and a bolt bore in the door frame. The door frame security device includes a security plate adapted to be affixed to the inside portion of the door frame before installing the door frame. A reinforcing device for reinforcing the bolt bore may be interdependent with and extend from the security plate and may be positioned in-line and placed through the bolt bore. When the door is locked, the bolt passes through the strike plate and the bolt bore in the door frame and engages the reinforcing device that extends from the security plate. The bolt, security plate and reinforcing device jointly resist impact forces on the door.

Claims

1. A door frame security device, the door frame having an inside and an outside portion, the outside portion having a strike plate affixed thereto, the strike plate being adapted to mate with a bolt of the door as the bolt passes through it and a bolt bore in the door frame, the door frame security device comprising:

a security plate adapted to be affixed to the inside portion of the door frame before the door frame is installed within an opening of a wall; and

means for reinforcing the bolt bore, said reinforcing means adapted to be interdependent with and extend from said security plate and positioned in-line and through the bolt bore when said security plate is affixed to the door frame;

wherein when the door is locked, the bolt passes through the strike plate and the bolt bore and engages said reinforcing means which extends from said security plate, thereby the bolt, said security plate and said reinforcing means jointly act to resist any impact forces applied to the door.

2. The door frame security device of claim 1 wherein said means for reinforcing the bolt bore comprises a tab member extending perpendicularly from said security plate.

3. The door frame security device of claim 1 wherein said security plate further comprises a through-hole adapted to receive a fastening means to affix said security plate to the inside portion of the door frame.

4. The door frame security device of claim 1 wherein said security plate further comprises a through-hole adapted to receive a security fastening means used to affix the strike plate to the outside portion of the door frame.

5. The door frame security device of claim 1 wherein said security plate further comprises a through-hole adapted to receive the bolt.

6. The door frame security device of claim 1 wherein said security plate and said means for reinforcing the door frame are comprised of a unitary material.

7. The door frame security device of claim 6 wherein said material comprises steel.

8. The door frame security device of claim 7 wherein said steel is galvanized.

9. A door frame security device, the door frame having an inside and an outside portion, the outside portion having a strike plate affixed thereto, the strike plate being adapted to mate with a bolt of the door as the bolt passes through it and a bolt bore in the door frame, the door frame security device comprising:

a security plate adapted to be affixed to the inside portion of the door frame before the door frame is installed within an opening of a wall; and

a tab member adapted to be interdependent with and extend perpendicularly from said security plate and positioned in-line and through the bolt bore when said security plate is affixed to the door frame;

wherein when the door is locked, the bolt passes through the strike plate and the bolt bore and engages said tab member which extends from said security plate, thereby the bolt, said security plate and said tab member jointly act to resist any impact forces applied to the door.

10. The door frame security device of claim 9 wherein said security plate further comprises a through-hole adapted to receive a fastening means to affix said security plate to the inside portion of the door frame.

11. The door frame security device of claim 9 wherein said security plate further comprises a through-hole adapted to receive a security fastening means used to affix the strike plate to the outside portion of the door frame.

12. The door frame security device of claim 9 wherein said security plate further comprises a through-hole adapted to receive the bolt.

13. The door frame security device of claim 9 wherein said security plate and said tab member are comprised of a unitary material.

14. The door frame security device of claim 13 wherein said material comprises steel.

15. The door frame security device of claim 14 wherein said steel is galvanized.

16. A door frame security device, the door frame having an inside and an outside portion, the outside portion having a strike plate affixed thereto, the strike plate being adapted to mate with a bolt of the door as the bolt passes through it and a bolt bore in the door frame, the door frame security device comprising:

a security plate adapted to be affixed to the inside portion of the door frame before the door frame is installed within an opening of a wall; and

a tab member adapted to be interdependent with and extend perpendicularly from said security plate and positioned in-line and through the bolt bore when said security plate is affixed to the door frame;

said security plate further comprising a through-hole adapted to receive a fastening means to affix said security plate to the inside portion of the door frame;

wherein when the door is locked, the bolt passes through the strike plate and the bolt bore and engages said tab member which extends from said security plate, thereby the bolt, said security plate and said tab member jointly act to resist any impact forces applied to the door.

17. The door frame security device of claim 16 wherein said security plate further comprises a through-hole adapted to receive a security fastening means used to affix the strike plate to the outside portion of the door frame.

18. The door frame security device of claim 16 wherein said security plate further comprises a through-hole adapted to receive the bolt.

19. The door frame security device of claim 16 wherein said security plate and said tab member are comprised of a unitary material.

20. The door frame security device of claim 19 wherein said material comprises galvanized steel.
