Abstract: A split platform ladder stand is described for releasable attachment between selected adjacent upper and lower treads on a conventional ladder. The stand includes a first platform having a first user support surface and a bottom lower tread engagement surface. A stabilizer extends upwardly from the first platform to a stabilizer yoke having an upper tread engagement surface. A second platform has a second user support surface mounted for selective adjustment in relation to the first platform. The second platform is movable between an operative position wherein the second user support surface is substantially coplanar with the first user support surface, and an inoperative position wherein the second user support surface is positioned angularly toward the stabilizer.

Abstract: A ladder apparatus comprising a longitudinally elongated step support for mounting between an upper level and a lower level at a forward angle of inclination. The elongated support has an upper end and a lower end. A series of steps are mounted relative to the elongated support. A hinge assembly is mounted relative to the elongated support adjacent its upper end. The hinge assembly includes a pivot positioned adjacent one of the outer longitudinal edges enabling the ladder apparatus to be swung at least about 90.degree. between an operable position and a stowed position. The hinge assembly preferably comprises retaining means for inhibiting the ladder apparatus from swinging away from the operable position.

Abstract: An alternating tread ladder apparatus and an associated tread step bracket are disclosed. The apparatus comprises an elongated central tread support for mounting between a upper level and a lower level at some predetermined forward angle of inclination. The tread support is provided with a plurality of generally laterally oriented tread support apertures positioned therealong and extending therethrough. The preferred embodiment tread step brackets are comprised of angled Z-shape. The upper arm of the Z is longer than the lower arm, and entends through one of the apertures in the central tread support.
