Title: Matthias Steffen: Innovator in Passenger Conveyor Technology
Introduction
Matthias Steffen is a notable inventor based in Kirchbrak, Germany. He has made significant contributions to the field of passenger conveyor technology, holding a total of 3 patents. His innovative designs focus on enhancing the safety and functionality of escalators and moving walkways.
Latest Patents
One of his latest patents is for a passenger conveyor handrail that features a gripping surface with a generally circular cross-section. This design includes a toothed driven surface that can be engaged by a toothed driving member, allowing for efficient propulsion of the handrail in the desired direction. The circular cross-section extends along the entire length of the handrail, corresponding to the closed loop path followed during operation.
Another significant patent involves a detection system for missing steps in escalators or moving walks. This system utilizes a mechanical sensor positioned beside the return run of the steps. The sensor is designed to bear against each step as it passes. If a step is missing, the sensor will move and open a switch in the escalator's power circuit, shutting off power to the escalator. This switch can only be manually reset by a mechanic from a location that is inaccessible to the public.
