ABSTRACT:
An emergency escape window provides a large unobstructed opening for escape from a room during an emergency. The window unit includes a window frame for positioning in a window opening in a wall and fastening to the wall. The window unit has window lights contained in a jamb which fits inside the frame. A hinge is fastened to one frame member and the adjacent jamb member so that the jamb is pivotally movable relative to the frame between a closed position at which the jamb is flush with the frame and an open position at which the jamb is displaced from the frame. Vertical frame and jamb members opposite the hinge are tapered to prevent binding during opening and closing. A locking mechanism is attached to the jamb to lock the jamb and frame in the closed position. Operating the locking mechanism causes the jamb to swing away from the frame like a door to provide an opening for escape.
