This is a system that allows a small child to escape from a window well using a ladder and a window well cover. The ladder extends from the bottom of the window well cover and has a trigger that when activated slides the ladder and releases a trap door in the window well cover, thus allowing a person to climb the ladder and escape through the cover.
