US Patent:
4592270, Jun 3, 1986
Filed:
Jul 16, 1984
Appl. No.:
6/631256
Inventors:
Alvin S. Vener - Houston TX
International Classification:
F24F 1100
US Classification:
98 391
Abstract:
A smoke and fire protection system is disclosed for elevators in a multistory building having an elevator hoistway therein, with an elevator cab having vertical movement therein. The hoistway is preferably enclosed at the top to prevent discharge of smoke therethrough. A duct is positioned in the hoistway connected to the elevator cab throughout its entire range of vertical movement and has an elongated opening extending for the full height thereof and sealed by a pair of elongated strips of flexible material along each edge of the opening meeting in sealing relation. A duct of elongated cross section and bell shaped is secured on the cab and fits through the sealing strips at the point of contact therebetween for movement with the cab along the length of the elongated opening with the sealing strips maintaining sealing relation ahead of and behind the elongated bell shaped portion. A blower connected to the duct supplies fresh air to the elevator cab and may include heating, cooling, and filtering apparatus for conditioning the air supplied therethrough. The blower supplies fresh air at a volume and pressure sufficient to ventilate the cab and effect a substantial outflow of air on opening the elevator and hoistway doors.
