METHOD OF TRANSPORTATION OF CARGO IN BUILDINGS AND DEVICE FOR ITS REALIZATION Russian patent published in 1994 - IPC

FIELD: evacuation of cargo from buildings, mainly from public buildings, for example, in case of fire. SUBSTANCE: method involves transportation of cargo through tube-type carrier which is made from flexible material of specified structure and having diameter which is smaller than transverse dimension of cargo. Cargo is evacuated to ground due to gravitational force, but in this case motion of cargo is decelerated because of cargo friction against flexible expanded walls of carrier to exclude cargo damage. Desired speed of transportation of cargo is ensured by regulation of composition of material and its parameters. Carrier is composed of sections to provide evacuation of cargo from all stores simultaneously. EFFECT: enhanced reliability. 7 cl, 2 dwg
