<p>#CMT# #/CMT# The staircase has an adjusting device for adjusting a bottom plate, and for adjusting stairs positioned between two positions. A pair of step sections is equipped with continuous axes and tilt axes (6, 7) that are positioned relative to continuous line parts. Plate parts (8, 8') are positioned between center of tube sections and center of length (L) of a hole, where the length of the hole corresponds to radius of curvature (R) of a head of the line parts. An edge of a tread part (2) produces a converted edge parallel to a wall (1). Sheet metal parts are provided with a slot (S). #CMT#USE : #/CMT# Staircase for a swimming pool (claimed). #CMT#ADVANTAGE : #/CMT# The staircase has high torsional stability. The sheet metal parts provide the simple and folding construction for the staircase. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a perspective view of a staircase.
