PURPOSE:To enable a staircase assembly to be reversed with a simple construction by two reversing frames pivotable by 90 deg. and having the L-shaped cross section. CONSTITUTION:An apparatus for reversing a staircase is provided longitudinally with two reversing frames having two staircase mounting surfaces comprising roller tables and L-shaped cross section so that the respective reversing frames are separately reversed by 90 deg. to provide 180 deg. reversal. Thus, the construction is simplified, needing no cramp mechanism, so that a compact apparatus is provided. |
