Abstract
A retractable additional half step for use with a flight of stairs comprises a plank 1 attached at one end by a hinge 2 to a side panel 3 provided with holes for fastening to a staircase side wall 4. The other end of the plank 1 is fixed to a riser board 5 designed to stand erect on a stair tread 6 when the half step is deployed. The hinge 2 enables the plank 1 to be folded up against the side wall up to clear the flight for normal use. The additional half step can help users with weak legs strong enough for half a stair rise. The side panel; and riser board may be the same height so that the device is self-aligning and levelling for quick DIY installation. The half step may be held securely in the retracted, folded up position by provision of magnetic or catch holding means. The riser board may be fixe to the plank by hinges so that it folds down against the plank when the half step is retracted by folding up.
Description
