Abstract: Air deflectors are mounted on the top and bottom of the counterweight assembly in an elevator system to deflect air in the elevator hoistway to the sides of the counterweight as the latter moves up and down in the hoistway. The deflectors ensure that air turbulence is not directed toward the car as the car and counterweight pass each other in the hoistway. A quieter and smoother passenger ride is thus accomplished. In an ultra high-speed elevator system, the counterweights may be completely enclosed in an aerodynamic jacket. Cable connections and compensating rope connections to the counterweight are all made inboard thereof to ensure that the counterweight is free of turbulence-inducing protuberances.

Abstract: Air deflectors 46 are mounted on the top and bottom of the counterweight assembly 2 in an elevator system to deflect air in the elevator hoistway to the sides of the counterweight as the latter moves up and down in the hoistway. The deflectors ensure that air turbulence is not directed toward the car as the car and counterweight pass each other in the hoistway. A quieter and smoother passenger ride is thus accomplished. In an ultra-high-speed elevator system, the counterweight assembly may be completely enclosed in an aerodynamic jacket (50, Fig. 4). Cable connections and compensating rope connections to the counterweight are preferably all made inboard thereof to ensure that the counterweight is free of turbulence-inducing protruberances.
