Abstract

DC60 (21/04/42) A reflector, which has a number of grooves created on the periphery and stretched out in the axial direction of that segment. And the irregular parts that are created on the edge Around the inside of that section To provide a tight overlap of the upper reflector Each cross-section of the staircase Reflectors are easily attached to each cross-section. And can be massively seized To prevent accidents When the user will go up or down the stairs A staircase equipped with a reflector has a pair of beams, a number of cross-sections arranged between and to the beam. And the pieces that cross each other but Each piece has a number of grooves arranged on the perimeter. And stretched out in the direction The axial way of that section Reflectors are placed on at least one end. Of each cross-section, the interconnection between the cross-section and the beam, and each reflector Will be shaped into a ring And there is no part A certain amount of uniformity is created on the inner perimeter in a section with a diameter size. Small part of that Which will overlap in the groove of the cross-sectional parts A reflector portion with an irregular portion is also created on the inner rim of the reflector in A section with a large diameter of that section And a number of grooves will be built on Periphery And stretched out in the axial direction of that part Reflectors, which have a number of grooves that are created on the periphery and stretched out in the axial direction of the segment.
