Abstract

A fire escape means is provided comprising a moveable cart for storing and, when needed, moving a fire escape into position for deployment out of a building, the fire escape having an upper, supporting entry ring 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 ring member attached to the lower end of the mesh tube. During storage, the fire escape is folded into the cart. The building is provided with at least one opening through which the fire escape is to be deployed. To the building near this opening is permanently attached a guide wire which extends from the opening at a desired angle to the ground where it is permanently affixed to a rigid support on the ground. To the lower ring support member, one end of a leash means is attached, the leash means having a snap-on mechanism removeably engageable to the guide wire attached to the other end. When escape is necessary, the cart is moved to the opening, the lower support member is attached to the guide wire by means of the snap-on leash, the lower support member then slides down the guide wire and the fire escape tube is deployed. Preferably there is a latch mechanism affixed to the rigid ground support which is capable of receiving and latching the snap-on mechanism and affixing it to the ground support when the lower support member descends to the ground. Once deployed, the fire escape tube can be descended by a person or persons to escape a fire in said building.
