Abstract

An easy out fire escape window gate comprising a gate frame mounted to a window frame of a window on an inner side of an exterior wall of a building. A pair of protective shutters are provided. Components are for connecting opposite sides of the protective shutters to opposite sides of the gate frame. The protective shutters can swing to an open position and a closed position. A structure is for locking the protective shutters to the gate frame in the closed position, to prevent an entry through the window from the exterior of the building to reduce burglaries. A facility is for quickly unlocking the protective shutters from the gate frame. The protective shutters can go into the opened position, to allow people within the building to safely exit through the window during a fire.
