Abstract: An improved stair nosing device especially useful in temporarily darkened stairways is provided which includes a plate member with an upper surface, at least a portion of which is covered by luminescent material. The stair nosing device includes non-slip material attached to the upper surface to provide increased frictional contact with foot traffic relative to the plate member. The non-slip material is attached as spaced apart strips with an upper surface of the non-slip material being higher relative to the plate member. In this way the luminescent material is protected from damage by foot traffic.

Abstract: A floor mat is disclosed which provides a flexible, resilient, cushioned, tread surface and substantial foreign matter collection area. The preferred floor mat includes a plurality of elongated, flexible, resilient, spaced-apart, intercoupled rails. Each preferred rail includes a plurality of elongated, upstanding, spaced-apart cleaning structures extending upwardly from the rail top surface with a transverse wall between adjacent cleaning structures which together cooperatively define respective collection troughs. Each transverse wall includes a plurality of foreign matter removal openings and each rail includes a plurality of elongated, longitudinally disposed passageways extending substantially along the length of each rail and positioned respectively beneath a corresponding cleaning structure for cushioning impact on the cleaning structures.
