Introducing the "Autodoor"

It took several years of innovation and trial and error to perfect the automatic door mechanism that we enjoy today. In 1946, Dee Horton and Lew Hewitt introduced the first fully automated door called the "Autodoor."

The Autodoor consisted of a series of sensors and machines that operated the opening and closing of the doors. As soon as a passenger entered the elevator and pressed the button for their desired floor, the doors would open automatically, letting them in. No manual intervention was necessary, enhancing passenger safety, and speeding up travel times.

The innovation quickly caught on, and soon elevator manufacturers around the world sought to improve the technology further. Today, automatic doors are a standard feature in all elevators, adding safety, convenience, and a touch of modernity to vertical transportation.

The Technology behind Automatic Elevator Doors

The modern-day automatic door technology works on simple principles of automation. The elevator doors are equipped with sensors such as infrared, motion detectors, or pressure sensors, which detect the presence of passengers in the vicinity. As soon as these sensors pick up movement, they send a signal to the control panel to open or close the doors.

The control panel, in turn, operates the motor that controls the movement of the doors. The motor moves the doors horizontally using a rotational spindle that is connected to the metal frame of the doors. The metal frame is attached to the guide rails that enable the doors to slide horizontally, ensuring a smooth opening and closing mechanism.
