Abstract (en)
A handrail which, intended to connect the uprights of a spiral staircase, is formed in assembly with a bundle of strips (1,4,8,11,13,16,21,26,35,36,37) with low thickness and simply placed adjacent so as to easily curve them manually according to the helicoid passing through the uprights (2,5,9,12,14,20,25,30,32,34) already fixed to the staircase and the head whereof, shaped according to the transverse profile to be imposed to the bundle which rests thereon, allows the transverse perforation of the handrail and the subsequent fixing to the uprights with coupling means (3,7,10,15,18,23,28) adapted to keep the strips rigidly adjacent.
