A planar handrail frame can be vertically erected and fixed on each edge of the work floor. The handrail frame can be rotated within its vertical plane in such a manner that a horizontal axis passing through an approximately central part of a sill of the erected handrail frame and perpendicular to the handrail frame is set to be the axis of rotation.SELECTED DRAWING: Figure 12 |
