Abstract (en)

[origin: EP0263600A2] A spiral staircase including a handrail (1) of tubular flexible construction together with a clamping means (2) comprising a cradle support (8) and an endless loop of cable (9) to mount the handrail (1) to a baluster (3). The cable (9) is passed over the handrail (1), the two runs of the loop (9) being located in a spiral groove (6) of the handrail so that the loop (9) does not stand proud of the handrail (1). When the cable (9) is tensioned the handrail (1) is firmly clamped to the cradle. The handrail being flexible and in need of alignment it is desirable that the connection between the vertical balusters and the outer ends of the stair treads of the spiral staircase provides for vertical adjustment of the balusters relative to the stair treads. Therefore, there is also provided a baluster mounting bracket including an elongate member (40) comprising an end part (40a) adapted to be slidably mounted in a channel or groove provided in the outer edge of a stair tread (4), a central collar part (40b) slidably engagable with a vertical baluster (3), the other end part (40c) of said member (40) being adapted to be clamped to said channel or groove, and clamping means (42, 43, 44) for clamping the other end part (40c) of said member (40) to said channel or groove, thereby to clamp the baluster (3) to the stairtread (4).
