Abstract

A passenger conveyor handrail (30) has a gripping surface (32, 42, 52, 62, 72, 82) with a generally circular cross-section. Disclosed examples include a toothed driven surface (34, 44, 54, 64, 74, 84) that is adapted to be engaged by a toothed driving member (28) for propelling the handrail in a desired direction. Disclosed examples include having the generally circular cross-section extend along an entire length of the handrail (30) corresponding to the closed loop path followed by the handrail during operation of a corresponding passenger conveyor.
