  • Patent number: 5085293
    Abstract: A sealing apparatus has inflatable hallow body portions extending around a car opening to close off the space between an elevator shaft wall and the car opening of an elevator car in a draftsproof and weatherproof manner when stopping at a floor. After the car stops at a floor, a pressurized fluid medium is utilized to inflate the hollow body until it is pressed against the shaft wall. The hollow body of the sealing apparatus is ventilated to atmosphere or to a vacuum before the departure of the elevator car from the floor such that the hollow body retracts so as to assure the spacing which is necessary for the free travel of the elevator car in the shaft. The sealing apparatus is monitored for low and excess pressure conditions.
