Life-saving chute for high rise building chute - has slender elongated tubes for escapees to grasp, also has flexible ladders

摘要

Improved life-saving chute for permitting vertical descent which is suitable for admitting escapes into the chute from various stories of a building. Chute has a number of descending passages, each of which is composed of a vertically oriented flexible tubular member and a bottom member perpendicular, and disposed in any one of a number of vertically oriented columns in its condition of use. The chute may have rigid members at the positions of the bottom members so as to always maintain the outer configuration of the bottom members, which may be rigid. The chute may have only a pair of the columns such that the descending passages are disposed alternately within the columns. At least one of the descending passages, except the uppermost one, may be opened directly to the outside so as to admit escapes.
