Abstract
A handrail positioning apparatus for use along a stairway is disclosed. The apparatus provides a pivot support fixed to a wall or other support structure to allow positioning of a handrail at at least two different laterally displaced positions. One position can be provided so that the positionable handrail is as close as 22 inches from a second, fixed position handrail disposed opposite the positionable handrail along the stairway. A second position of the handrail occurs in a vertically folded position of the pivoting apparatus bringing the handrail into a position substantially adjacent the support structure, which opens the stairway to about its full width.
