Abstract
A passenger conveyance tread member, which may be for an escalator or a travelling road, has a tread surface with lateral edges having surfaces which slope towards skirt guards adjacent the lateral edges. The sloping surfaces and skirt guards define a downwardly narrowing gap so that the tendency of e.g. shoes to get seriously stuck in the gap is reduced. The sloping surface may be on a side-most cleat of the tread. An existing conveyance may be adapted by providing its tread members with such sloping surfaces at their edges, e.g. as an insert strip.
