Abstract
An automatic storm shutter. A shutter is hingeadly attached to a wall over a structure opening. An actuator is attached to the shutter, and releasably engaged with a support, which is rigidly attached to the wall. When external atmospheric pressure descends, as would happen at the approach of a wind storm such as a tornado, gas pressure within the actuator automatically releases the actuator from the support, which permits the shutter to quickly close as urged by gravity, to cover the structure opening and protect it from storm winds. An alternate embodiment is disclosed wherein one or more additional shutters are installed below the automatic storm shutter. The shutters are mutually attached with an elongate member. When the automatic storm shutter automatically closes, so also do the shutters below.
