  • Patent number: 5239796
    Abstract: A staircase cabinet comprises a plurality of treads each having an outer edge, an inner edge and a back surface; a pair of outer stringers both for defining opposed walls of the cabinet and supporting the outer edges of each tread; an inner stringer for supporting the inner edges of each tread; and fasteners for attaching the treads to the inner stringer and the outer stringers in alternating arrangement on respective opposite sides of the inner stringer to define an alternating staircase for use between a lower level and an upper level, the back surface of the treads and the outer stringers defining a cabinet space. The outer stringers comprise planar wooden sheets having an outer surface, and the fasteners pass only partially through the planar members to maintain the outer surface unbroken by the fasteners.
