Abstract

Die Erfindung betrifft eine Treppe (1) mit einer ersten Wangenstruktur (2) und einer zweiten Wangenstruktur (3), wobei die Wangenstrukturen (2, 3) über Stufen (4) miteinander verbunden sind und jede Wangenstruktur (2, 3) bezüglich einer Längserstreckung der jeweiligen Wangenstruktur (2, 3) in Reihe zueinander angeordnete, paarweise miteinander verbundene Wangenelemente (5, 6, 7) aufweist. Um eine Treppe (1) mit variabel einstellbarer Steigung bereitzustellen, sind in Höhenrichtung der jeweiligen Wangenstruktur (2, 3) verlaufende, einander zugewandt angeordnete vertikale Verbindungsseiten (14, 17) von wenigstens einem Paar aus benachbart zueinander angeordneten Wangenelementen (5, 6, 7) der jeweiligen Wangenstruktur (2, 3) über wenigstens eine in Höhenrichtung der jeweiligen Wangenstruktur (2, 3) verlaufende Verbindung verstellbar miteinander verbunden.The invention relates to a staircase (1) with a first cheek structure (2) and a second cheek structure (3), the cheek structures (2, 3) being connected to one another via steps (4) and each cheek structure (2, 3) being connected to one another in a longitudinal direction of the respective cheek structure (2, 3) arranged in series with one another, cheek elements (5, 6, 7) connected to one another in pairs. In order to provide a staircase (1) with a variably adjustable incline, vertical connecting sides (14, 17) of at least one pair of side-by-side elements (5, 6, 7) that run in the height direction of the respective cheek structure (2, 3) and are arranged facing one another are required ) the respective cheek structure (2, 3) are adjustably connected to one another via at least one connection running in the height direction of the respective cheek structure (2, 3).
