Description

Embodiments of the present invention relate to passenger conveyors.

In recent years, preventive measures against infectious diseases such as novel coronaviruses and influenza viruses have been encouraged. Therefore, measures are taken to avoid contact infection in places where there is a risk of people crowding together. For example, in commercial facilities and office buildings, alcohol dispensers for disinfecting hands and fingers are installed at entrances, and shielding plates and shielding sheets are installed to prevent droplets from scattering.

2. Description of the Related Art In commercial facilities, transportation facilities, and the like, an escalator for moving upstairs and an escalator for moving downstairs are often arranged adjacent to each other. In particular, an escalator installed in a subway or the like has a high lifting height, which may require a long boarding time. They are also installed in relatively closed spaces with low ceilings. In this case, the passengers of each escalator will face each other for a long time, so it is necessary to take measures to prevent droplet infection between passengers due to sneezing or coughing.

The space in which the escalator is installed is relatively large. Therefore, it is conceivable to use an air curtain to spatially separate escalators installed adjacent to each other. Conventionally, however, air currents have only been created around passengers by blowers installed on the ceiling or the like.
