摘要: A double deck elevator comprising an upper cage and a lower cage vertically movable together in a hositway, wherein a space between the upper cage and the lower cage is covered by covers. The covers guide airflow flowing around the space to reduce air turbulence noise, and consequently the quietness and comfortableness in the cages is improved.
