Abstract:
The disclosed preferred embodiment of the handrail cleaning device comprises a flexible bar which uses spring resilience force to press one or more reusable or disposable cleaning pads against the moving handrail of an escalator. The apparatus provides a lightweight, low cost apparatus that is simple to set-up and use and requires no external power. Additionally, the device is capable of cleaning and treating the handrails of common escalators during operation of the escalator. The device utilizes the motion of the escalator to perform the cleaning action. The simplicity of the device allows for multiple devices to be used simultaneously by a single operator.

Claim (Index 11):
A method for cleaning an escalator and a travelator handrail comprising:\n providing a cleaning apparatus to an escalator hand rail comprising:\n a spring arm; \n one or more cleaning pads; wherein the one or more cleaning pads are removably affixed to the spring arm, wherein the cleaning pads are deformable and shaped to firmly mate with the rubber portion of the handrail, wherein the spring arm comprises at least a vertical positioning portion and a radial positioning portion; \n placing the cleaning apparatus in a position relative to the handrail at an exit newel of the escalator and the travelator that both of the vertical positioning portion and the radial positioning portion are in a flexed posture adjacent to the handrail such that the cleaning pads can be adjusted; \n adjusting the cleaning pads for optimal fit on the handrail; \n placing the cleaning pads into position on the moving handrail; and \n releasing flexure on the spring arm such that resiliency of the spring arm is transmitted to the cleaning pad assemblies to have cleaning pressure on the handrail.
