A window escape comprises a sturdy housing secured to a building wall above a window or the like. The housing has an open bottom and a rotatable sleeve supported between two side walls. A cover is removably retained over the front of the housing. A long rope is tied at one end to the sleeve and at the other end to the cover. Normally the rope is wound around the sleeve and is hidden from view by the cover. In an emergency, a person removes the cover from the housing and throws the cover out the open window. The falling cover unwinds the rope from the sleeve. After the rope is unwound, the person can easily grasp it and descend to safety.
