Abstract

A hurricane shutter escape mechanism for allowing fast and easy removal of conventional hurricane shutters from a window or door of a structure in the event of an emergency. The device comprises a release member, an anchor, a removable stud for engaging and securing the hurricane shutters, and a spring-actuated panel fastener that includes a leaf spring to engage and hold the removable stud in position. The release member includes a slot having a small aperture to hold the stud in position and a large aperture to release the stud from the anchor. From inside the building, the release member is pushed down to release the hurricane shutters so that the occupants of a structure can escape during an emergency, such as a fire. From outside the building, a rescuer can depress the leaf spring to remove the spring-actuated panel fastener, and thereby, also remove the hurricane shutter panel.
