Safety escape bag

Claim 1

An escape device comprising an elongated tubular body adapted to be supported at its one end in a position to extend vertically downwardly and including an opening at its upper end for receiving an escaper, a closed flat bottom at its lower end for catching thereon the escaper who has fallen through the body and an opening provided laterally to the wall of said elongated tubular body adjacent to its lower end for the escaper to exit from the body, and means to prevent the fall through said tubular body of a second escaper while a first escaper is in said escape device, said tubular body comprising a series of pliant tubular columns having diameters sufficient for allowing an escapr to pass through and connected by resilient portions made of spiral meshes, said resilient portions comprising said means to prevent the fall of a second escaper, each said resilient portion having a diameter smaller than those of the tubular columns and being radially expandable to such an extent that the free fall and downward speed of an escaper are resisted and reduced, each said resilient portion being longitudinally expandable to such an extent that it can completely prevent the fall of the second escaper therethrough when the first escaper has been caught on the closed flat bottom and his weight is added to the device, thereby preventing two escapers from colliding each other at the lower end of the device.
