Abstract (en)
[origin: EP0146677A2] Stairways of wood without risers have the disadvantage of easy excitability of self-induced vibrations, which lead to a feeling of insecurity in the stairway user and to the annoying development of noise. The aim is to minimise these vibrations and to permit rapid mounting on site. According to the invention, provision is made for at least the stairs (2) provided between the first and last stair to be equipped with a plurality ... of a bolt and a sleeve (13) receiving the latter and of a resilient bushing (14) encompassing the sleeve, in each case the bolts (12) and the sleeves (13) being arranged over part of their length in a parallel position with respect to the stair plane, and the resilient bushing (14) being arranged at an angle of low inclination with respect to the vertical of the wall. On the banister side, supporting elements, in each case separating two stairs, in the form of tubular wooden supporting blocks are provided in separating-bolt constructions (6), the distance between which is set so that after securing the inner periphery of the upwardly inclined bushings, said bushings assume a position in the horizontal. <IMAGE>
