ABSTRACT:
A window guard assembly has features that allow it to be released from the inside to allow occupants to escape in case of fire. The window guard assembly also has features that prevent the locking mechanism from being actuated by an intruder on the outside of the building. The guard assembly has a guard mounted to a window frame for covering a window. The guard is pivotally mounted, and a locking mechanism selectively prevents the pivoting of the guard. A latch member controls the locking mechanism. An enclosure is formed around the latch member to prevent access from the exterior. The enclosure has an opening that faces the interior. A pair of doors are located at the opening, one with a vertical hinge, and the other with a horizontal hinge. Both of these doors require opening to reach the latch member. When opened, the doors form a barrier in cooperation with the window frame that requires the intruder to attempt to reach around the doors in order to reach the latch member.
