Abstract (en)
Treading elements (2) can be jointly adjusted out of a position of stairs into a surface forming a footbridge or walkway and vice versa. Set up to swivel on a side axle (26) extending at right angles to lengthwise supports (3,4), the treading elements also have on a side end a connecting stay (9) designed as a lever to link to an adjusting device's (13) selector rod (12).
