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 21):
An escalator and a travelator cleaning apparatus that has a self-adjustable spring arm operable to enable at least one cleaning pad to contact the handrail of the escalator and the travelator that have different constructions of the exit newel as the handrail curves from its upward facing position around a curved reversing portion comprising:\n a spring arm of a single continuous length made of a flexible resilient material having;\n a floor resting 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 merging at the distal end of the floor resting length and curved to a substantially opposite direction where it merges to a vertical adjusting arm which is adapted to extend toward the handrail to a proximal end the proximal end having allowed vertical movement substantially by flexing of the vertical position adjusting curve and a radial adjusting curve merging from the proximal end of the vertical adjusting arm and an upper arm defining a merging from the radial adjusting curve and extending distally upwardly to a distal termination and the upper arm having at least one mounting position for mounting a cleaning pad and a cleaning pad mounted on the at least one mounting position; \n whereby flexing of the spring arm by a downward force at the distal termination provides flexing of both the vertical adjusting curve and the radial adjusting curve such that the upper arm will self-adjust upon release of the downward force to bring the cleaning pad into cleaning position at the handrail.
