ABSTRACT:
A burglar guard for windows and doors is constructed of unbreakable, bullet-resistant transparent sheet material such as polycarbonate or Lexan plastic. The window guard comprises a generally planar, rectangular transparent sheet member having apertures in each of its corners which is installed on the interior of the building and covers existing conventional windows. Threaded studs are mounted in the wall studs adjacent to the existing window frame and the window guard is installed thereon by means of washers and threaded knobs for quick and easy installation and removal. A door guard is also constructed of the same unbreakable, bullet-resistant transparent sheet material and comprises a generally square, box shaped member enclosed on five sides. The door guard is installed on the exterior surface of the door and covers the existing conventional door knob. Holes are drilled through the door and rods integral with the door guard are inserted therethrough to protrude beyond the interior surface of the door and secured in position by knobs or pins installed on the ends of the rods. These guard attachments are inaccessible from the exterior of the building, but easily and quickly removed by an occupant from the inside.
