Title: Innovations by Hans-Jurgen Langer
Introduction
Hans-Jurgen Langer is a notable inventor based in Hespe, Germany. He has made significant contributions to the field of escalator technology, holding a total of 2 patents. His work focuses on enhancing safety and reducing noise in escalator systems.
Latest Patents
One of Langer's latest patents is the "Noise Reduced Step Chain Sprocket." This invention addresses the noise generated by the engagement of the drive sprocket and the step chain in escalators. The sprocket features an overlay that cushions the chain as it engages the sprocket teeth, minimizing noise. Additionally, a plate provides lateral support for the overlay during engagement.
Another significant patent is the "Escalator Skirt Panel." This innovation increases safety in the area of running clearance between the step and the skirt panel of an escalator. It includes an elongated tubular bladder that runs the length of the skirt panel. If an object becomes trapped between the step and the panel, the inward deflection of the skirt panel increases the air pressure in the bladder. A sensitive switch controls the escalator's drive motor and applies the brake when necessary.
