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 24):
A method of cleaning the moving handrail of an escalator and a travelator wherein the handrail moves at an exit newel from a substantially upward facing position around a curve to a substantially downward facing position comprising:\n providing a handrail cleaning device comprising:\n a spring arm of a single continuous length made of a flexible resilient material having; \n a floor plate length which is substantially flat adapted to be oriented on a floor adjacent to the handrail to be cleaned and having a length extending away from the handrail to a distal end; \n a vertical position adjusting curve commencing at the distal end of the floor resting length and curved to a substantially opposite direction where it is attached to a vertical adjusting arm which extends toward the handrail to a proximal end the proximal end allowed vertical movement substantially by flexing of the vertical position adjusting curve and a radial adjusting curve commencing at the proximal end of the vertical adjusting arm and an upper arm curving upwardly away from the handrail a selected degree of curvature to a distal termination the upper arm having at least one mounting position for mounting a cleaning pad; \n a cleaning pad mounted on the at least one mounting position; \n placing the spring arm in a position relative to the handrail wherein flexing of the vertical adjusting curve and the radial adjusting curve results in the at least one handrail cleaning pad being in cleaning contact position to the handrail; \n maintaining the cleaning pad in the cleaning contact position as the handrail operates to pass by the cleaning pad to effect cleaning contact of the cleaning pad to the moving handrail.
