摘要： A variable curvature and/or pitch handrail for the balustrade (railing) of a circular, spiral and curved stairway which is capable of being assembled on the site, comprising a plurality of relatively short-length, generally cylindrical handrail sections each having an axial bore therethrough, rotatable washer-form wedges adapted to be interposed between the sections of each pair thereof, an elongate cable adapted to be threaded through the bores of end-to-end related sections and the center openings of the washer-form wedges interposed therebetween, means for tensioning the cable in manner as to secure said sections and washers together to the form of a rigid handrail, said washerform wedges incorporating readily accessible means whereby they may be individually rotated with respect to one another and to the cylindrical handrail sections between which they are interposed thereby to ''''set'''' the curvature and/or pitch of the hand-rail to that desired.
