Fire escape ladder

摘要

A fire escape ladder which includes recessed steps which are mounted into an interior or exterior wall of a house, or the concrete walls of a basement, to provide an escape route to a window. When the ladder is used, the lock to the window is automatically released, and springs in the window frame cause the window to partially open. An associated smoke detector or a connection to the household smoke detector activates lights in the recessed steps and an audible alarm which aids in egress from a dark or smoke-filled building.
