Abstract
A combined stairway and platform used in scaffolding systems. A stairway and platform system includes a stairway having steps, a top landing platform and a bottom landing platform, wherein the top and bottom landing platforms are integrally formed with the stairway. The top and bottom landing platforms are attachable to a scaffolding frame. An upper and lower end panel, to which a handrail is attached, are configured to attach to the scaffolding frame.
Claims19
A stairway and platform system comprising:
- a stairway comprising steps, a top landing platform and a bottom landing platform, wherein the top and bottom landing platforms are integrally formed with the stairway, the top and bottom landing platforms are attachable to a scaffolding frame, and the top and bottom landing platforms include U-shaped brackets that are attachable to the scaffolding frame;
- a handrail attached directly to the stairway, wherein the handrail comprises an upper section that is configured to extend above the top landing platform, and a lower section that is configured to extend above the bottom landing platform;
- a lower end panel to which the lower section of the handrail is attached, the lower end panel being configured to attach to the scaffolding frame, wherein the lower end panel extends between vertical supports of the scaffolding frame;
- and
- an upper end panel to which the upper section of the handrail is attached, the upper end panel being configured to attach to the scaffolding frame, wherein the upper end panel extends between the vertical supports of the scaffolding frame, the lower end panel and upper end panel comprise at least two horizontal sections that extend between the vertical supports of the scaffolding frame, and the upper and lower end panels have U-shaped hooks at ends thereof that are configured to fit into protrusions formed on the scaffolding frame.
