PROBLEM TO BE SOLVED: To provide a novel stairway structure that enables a tread dimension to be secured without enlarging an installation space for a stairway inside a house, and furthermore enables both a healthy person and an elderly person to select a virtual step height dimension.SOLUTION: A sub-stairway 3 is installed adjacently to a main stairway 2 having a tread dimension of 210 mm or more and a step height dimension between 230 and 320 mm, thus keeping a virtual step height dimension to 160 mm or less when ascending and descending the stairway by stepping alternately on a tread 21 of the main stairway 2 and a tread 31 of the sub-stairway 3.SELECTED DRAWING: Figure 1
【課題】本発明は、住居内における階段の設置スペースを増やすことなく、踏面寸法を確保することができ、しかも、健常者と高齢者の二者が、実質的な蹴上寸法を択一的に選ぶことができる新規な階段構造を提供することを目的とする。【解決手段】 踏面寸法が２１０ｍｍ以上、且つ、蹴上寸法２３０〜３２０ｍｍとなされた主階段２に副階段３を隣接配置することによって、前記主階段２の踏面２１と前記副階段３の踏面３１とを交互に踏みながら行う昇降運動実行時における実質的蹴上寸法が１６０ｍｍ以下となるようにする。【選択図】図１
