Abstract:
A temporary tread insert and method for installation in a stairway framework during building construction. The temporary tread insert includes an insert body having an upper tread surface, a bottom surface and opposed side surfaces. A front end of the insert body has a substantially bullnose shaped curved surface. The upper tread surface has a notched surface extending along the upper tread surface. Also disclosed is the method of inserting the temporary tread insert into the stair pan of a stairway framework, where the stair pan includes a bullnose at a front end of the stair pan, and the bullnose has a portion extending laterally a distance into the stair pan. The temporary tread insert includes a notched surface. The method includes positioning the temporary tread insert above a bottom of the pan, inserting the notched end of the temporary tread insert beneath the laterally extending portion of the bullnose, and moving the rear end of the temporary tread insert downward until the notched end of the temporary tread insert engages the underside of the portion extending laterally from the bullnose.

Claim (Index 11):
A method of removing a temporary tread insert from a stair pan of a stairway framework, the stair pan comprising a bullnose at a front end of the stair pan, the bullnose including a portion extending laterally a distance into the stair pan, the temporary tread insert including a notched surface, the bullnose portion extending a distance into the stair pan engaging the notched surface of the insert body and wedging the tread insert between an underside of the laterally extending bullnose portion and a bottom of the stair pan, the temporary tread insert including an aperture adjacent a rear portion of the temporary tread insert, comprising the steps of:\n engaging the aperture by an instrument under the control of a user; lifting the rear portion of the temporary tread insert with the instrument, rotating the insert body and simultaneously disengaging the notched portion of the temporary tread insert from the underside of the laterally extending bullnose portion, continuing to rotate the temporary tread insert until the notched portion is no longer disposed beneath the underside of laterally extending bullnose portion, and removing the temporary tread insert from the stair pan.
