ABSTRACT:
Continuously self-adjusting handrail apparatus for transportation apparatus, such as escalators and walks, in which the handrail guide automatically responds to forces therein to reduce the magnitude of load induced forces which tend to dislodge the handrail from its guide. The curved guide section adjacent each newel of an associated balustrade is arranged to change its curvature and increase or decrease its length, as required, in response to such forces, with the forces being such that when one section increases its length, the other section reduces it length.
