Abstract (en)
[origin: JPH01146052A] PURPOSE: To simplify structure and to firmly and rapidly build up a staircase of optional form by connecting only plural kinds of completely finished standardized parts to constitute the staircase. CONSTITUTION: Handrail parts 2 connecting each connecting frame 1 are arranged at the upper ends of the required number of U-shaped connecting frames 1, and staircase steps 3 of specified shape are mounted and fixed into specified positions near the lower ends of the connecting frames 1 through clamp fittings. These elements are standardized, mass-produceable and economically manufactured and fitted to obtain an outdoor staircase usable without special structure substantially for an optional flight of stairs.
