<p>A MODULAR STAIRWAY SYSTEM FOR INSTALLATION ON STRUCTURES HAVING NON-LINEAR WALLS: This application discloses a modular stairway system for circular structures or other structures having non-linear walls. The invention comprises a plurality of first stringer means, a plurality of first connecting means for joining the first stringers, a plurality of second stringer means horizontally spaced from and parallel to the first stringer means, and a plurality of adjustable second connecting means for adjustably joining the second stringers such that the first and second stringers conform to the curvature of the structure. A plurality of stairs are horizontally interposed between the first and second stringers, and a stair mounting means for securing the stairs to the first and second stringers are provided. Also provided are mounting bracket means securing the first stringers to the structure and brace means for supporting the second stringer to the structure, whereby there is obtained a reversible sectional stairway system which can be easily installed on circular structures or other structures having non-linear walls.</p> |
