Title: Stair construction

Abstract: A stair construction in which a stair tread member is releasably clamped in position upon a pair of spaced tread support frame members in a manner such that a tubular sleeve of carpeting or other flexible tread covering material is simultaneously snugly, yet releasably, fitted in place on the tread member. The construction includes a pair of individual side frame assemblies in a parallelogram linkage form wherein the inclination of the prefabricated side frame assemblies can be adjusted as required in the field while maintaining the tread support frame members in a true horizontal position.
