Abstract
A double deck elevator comprising an upper cage and a lower cage vertically movable together in a hoistway, 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 ride in the cages becomes quieter and more comfortable.

A double deck elevator comprising:
- an upper cage and a lower cage mounted on a cage frame and vertically movable together in a hoistway;
- covers for covering a space between the upper cage and the lower cage and for guiding airflow along outer surfaces of the upper cage and the lower cage, said covers comprising door-side cover, lateral-side cover and backside cover;
- and
- a catching device for catching objects dropped through a clearance between a door-side inner wall of the hoistway and the upper cage, said catching device including
- a catching plate being capable of swinging about horizontal axis between a first position in which a distal end thereof contacts a door-side inner wall of the hoistway and a second position in which the distal end retracts from the door-side inner wall,
- a driving means for driving said catching plate so that said catching plate swings between said first position and said second position,
- wherein said catching plate in the second position guides the airflow together with the door-side cover so that the airflow flows smoothly along an outer surface of the door-side cover.
