Latest Patents
Langer holds a patent for an escalator step chain roller. This invention features step chain rollers equipped with an annular elastomeric tread mounted on the rim of the roller. The roller rim is designed with a recess or groove that accommodates the tread. The main body of the roller is made of metal, and the side edges of the roller interact with the escalator roller track as the roller moves along it. This design provides lateral guidance for the step chain, enhancing the overall performance of the escalator. By recessing the tread in the roller rim, Langer's invention increases the metal-to-metal side contact zone between the roller and track, resulting in a longer roller lift. The sides of the tread are offset from the roller recess, allowing for crack-free expansion of the tread.
