Abstract
A fire escape is provided having an upper, supporting entry member and a mesh tube attached to this upper support member, the mesh tube being substantially longer than the building height from which escape is necessary, and a lower, exit-opening support member attached to the lower end of the mesh tube. The mesh openings have a maximum dimension of about two inches. In use, the maximum dimension of the upper entry member is larger than the window or other opening through which escape is necessary. In use, the lower support member and attached mesh tube are lowered to the ground through the window through which escape is to be made. The fire escape is held in place by the upper support member which cannot pass through the window. A person escapes the building by entering the upper entry support member and lowering himself to the ground safely by means of his hands engaging the mesh. In alternate embodiments, the fire escape of this invention can be permanently mounted on the roof of a building or it can be mounted on a movable cart for storage and easy movement, when needed, to a desired escape opening in the building such as a window.
