Abstract
A nose edge of a step of a stairway is to be marked by a lighted strip which can be seen by a person going upstairs and by a person going downstairs. This is to be accomplished by a nosing bar assembly which comprises a single illuminating device and in which transparent covering means for such illuminating device are not liable to be strongly damaged or soiled. For this purpose covering for the illuminating device is so arranged below the level of the tread surface of the step that points of the surface of the covering means can be seen from a space which is disposed above the tread surface of the step and which in the downstairs direction is defined by a vertical plane which contains the front boundary line of the tread surface.
