Abstract
Una escalera provista con las superficies reflectantes incluye un par de vigas, una pluralidad de piezas transversales provistas entre y que conectan lasvigas, y cada pieza transversal tiene una pluralidad de ranuras provistas sobre la periferiaexte rna y que se extienden en la direccion axial de las mismas.Una superficie reflectante está colocada sobre por lo menos un extremo de cada pieza transversal en una porcion de conexion entre la pieza transversal y laviga respectiva, y cadasuperficie r eflectante está en forma de anillo y tiene una pluralidad de irregularidades formadas sobre la periferia interna en unaporcion de diámetro pequeno del mismo que acopla en las ranuras de la pieza transversal respectiva. Las porciones desuperficie ref lectante que tienenirregularidades están formadas también sobre la periferia interna de la superficie reflectante en una porcion de diámetro grande del mismo, y una pluralidad deranuras que se forman en la periferia externa y seextienden en la direc cion axial del mismo. Las superficies reflectantes se unen fácilmente a cada piezatransversal y pueden ser sostenidos confiablemente sobre la misma evitando accidentes cuando el usuario asciende o desciende la escalera.
