Title: Peter Lehmann and Escalator Safety Innovation.
Introduction
Peter Lehmann is an inventor associated with Stadthagen, Germany. His patent work addresses escalator safety by detecting objects caught between a moving step and the skirt panel.
Latest Patents
Lehmann is credited with 1 patent, titled “Escalator Skirt Panel.” The invention uses an elongated tubular bladder positioned behind the skirt panel, opposite the escalator step. If an object becomes trapped and pushes the panel inward, the resulting increase in air pressure activates a pressure-sensitive switch. The switch controls a relay that stops the escalator’s drive motor and applies its brake.
Career Highlights
Lehmann is associated with Otis Elevator Company. His patented design focuses on responding to inward panel deflection as a way to help reduce the risk of injury or damage in the gap between an escalator step and its skirt panel.
Collaborations
Hans-Jurgen Langer is identified as Lehmann’s coworker. The available information does not specify whether Langer collaborated on the patent.
Conclusion
Peter Lehmann’s “Escalator Skirt Panel” patent describes a pressure-sensitive safety mechanism designed to stop an escalator when an object presses against its skirt panel.
