ABSTRACT:
A handrail for transportation apparatus, such as escalators and moving walks, which includes an elongated, extruded elastomeric member having first and second wear strips fixed to inner surfaces of the elastomeric member for contacting a handrail guide. Each wear strip has a substantially U-shaped cross-sectional configuration, including a bight and spaced leg portions, and , in addition to providing low friction wear surfaces, the configuration aids the handrail in resisting derailment from a handrail guide. At least one leg portion of each wear strip has a plurality of spaced slots, or thin webs, which extend inwardly from the end of the leg to facilitate flexing of the elastomeric body member while traversing curved portions of a handrail guide. In another embodiment, a plurality of relatively short, discrete wear strips are spaced apart to collectively define an elongated wear strip, with the spacings being selected to function as flexiblity imparting slots.
