Elevators with no doors 8/31/2015 •

Elevators with no doors

Several decades ago when elevators ascended and descended at a slow pace, innovations had to be done to the current design to improve efficiency. The solution was the invention of elevators with no doors.


They are called paternosters. The idea is simple: hang multiple cabins on a cable, remove all doors and move the cabins with slow speed. That way people have the opportunity to jump on and off the cabin successfully. At the speed of 0.95 feet per second it did not seem like a challenge. Also, the new design solved the issue of spaciousness, allowing the door-less elevator to fit more passengers than the modern models.

These elevators were popular in England, but in the US they are hardly known . As a result of several tragic cases where children or elderly people did not have time to leave the elevator and their limbs got stuck, many companies began to avoid using paternosters. Some have survived to this day. For example, some Moscow administrative buildings use these "constantly moving" elevators and a 2015 survey showed that Germany has more than 200 registered and active paternosters.

I came across this type of elevator at the corporate headquarters of a very conservative publishing company. The executive greeted me in the lobby and we jumped on the elevator. When we stepped off, the executive, who came across as very propper with professonalally trimmed beard and spoke impeccable Hoch Deutsch (or propper German), said that they call it a "paternoster" or "Our Father", because you pray that you can get off it. He went on to say, But one day when I was an intern here., someone dared me to go up on one side and come down on the other upsidedown. I did it and am thankful to this day that the bosses did not find out."

LOL - "paternoster" is Latin for "Our Father" as in the "Our Father" or The "Lord's Prayer." Someone had a great sense of humor to name them that. :-)

I understand them, but I would still "Freak Out" due to its unusuallity. The American's with Disability's Act (ADA) would never let this be installed without a trip to the Supreame Court.
