<p>According to the present invention there is provided a door frame security device. Generally, door frames have an inside and an outside portion. The outside portion generally has a strike plate affixed thereto which is 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 may include 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. A reinforcing device for reinforcing the bolt bore may be included which is adapted to 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. As such, the bolt, the security plate and the reinforcing device jointly act to resist any impact forces applied to the door. Additionally, the bolt, the strike plate, the security fastener, the security plate and the reinforcing device together form an integrated and connected structural body around the bolt bore to strengthen the bolt bore area.</p> |
