It is possible to display the design of the display 38 more clearly to the passengers of the escalator and the people around it by raising the design. Note that when adhesive is applied to the entire surface 38b of the display body 38 and the display body 38 is adhered and fixed to the back surface of the riser 19, there is no gap between the riser 19 and the display body 38, and the display body 38 is clearer. The design of the display body 38 can float on the surface 26 of the riser 19.
- the illuminating device 16 is composed of, for example, a fluorescent lamp bridged on a member of the main frame 1 and a ballast installed in the main frame 1.
- the illumination illuminance inside the main frame 1 is arbitrary, but sufficient illuminance can be obtained by arranging a large number of two rows of fluorescent lamps arranged side by side in the longitudinal direction of the main frame 1.
- FIGS. 9 and 10 are side views for explaining the assembly procedure of the escalator step according to the first embodiment of the present invention.

It is fastened and fixed to the lower side 31c of the side reinforcing member 31 by bolts 37.
- a mounting nut 29b may be fixed in advance to the other end of the upper side 29a of the lower reinforcing member 29.
- one side end portion of the upper side 29a is fastened and fixed to the lower side of the side reinforcing member 30 disposed so as to be opposed by a bolt 36.
- the tread plate 17, the upper reinforcing member 28, and the lower reinforcing member 29 are connected between the brackets 18 arranged on the left and right, and are firmly integrated.
- a substantially rectangular opening 32 bordered by the reinforcing members 28 to 31 is formed.
- the riser 19 is fixed to the metal reinforcing member 20.
- the countersunk screws 39, 40 and 41 are attached from the surface 26 side of the riser 19 to the upper reinforcing member 28, the lower reinforcing member 29, the side reinforcing member 30 and Fasten and fix to 31 respectively.
- the riser 19 since the surface 26 side of the riser 19 is made of translucent FRP, it is possible to impart high designability to the riser 19. For this reason, the riser 19 itself serves as a display means, for example, an advertisement such as an in-store guide or a logo mark is displayed on the display body 38, and the escalator is harmonized with the architecture without using the display body 38. It can be used for various purposes such as serving as a part of the terrier, or as a warning means for the safe use of escalators by illuminating your feet. Compared to the conventional one, the entire surface 26 of the riser 19 is made of FRP, so it is long. There is also an advantage that there is no fear of discoloration or deterioration of design even when used for years.
- the riser section is required to have a predetermined strength and rigidity, and if all of them are manufactured by FRP, it becomes necessary to take a very large thickness, resulting in high cost and stable dimensional accuracy. Realization becomes difficult.
- the metal reinforcing member 20 is provided between the brackets 18 arranged on the left and right, and the FRP riser 19 is fixed to the metal reinforcing member 20, so that The riser 19 can be formed of a thin plate-like member, so that the production efficiency can be improved and the cost can be reduced.
- the metal reinforcing member 20 can be arranged in a simple configuration by arranging it against the upper and lower edges of the back surface of the riser 19 or arranging it against the peripheral edge of the back surface of the riser 19.
- the reliability of Step 12 can be secured by using an adhesive in addition to fastening screws and bolts, etc., as described above.
- the riser 19 does not require high friction resistance unlike the tread surface 23 of the tread plate 17 that is always stepped on by passengers. Furthermore, since it does not correspond to the part where passengers get on, it does not require the performance to prevent slipping as required for the tread surface 23 of the tread plate 17, and conversely, it is low from the viewpoint of preventing being caught between the steps 12. A coefficient of friction is required. Therefore, if only the riser 19 that requires no surface coating to improve wear resistance and obtain a high coefficient of friction on the FPR material of the riser 19 is used as an FRP, it will be light and easy to use. It is possible to improve.
- step 12 of the above configuration is adopted for an escalator, for example, all of the steps are set to step 12 of the above configuration, some of them are set to step 12 of the above configuration, and other steps are conventionally performed. It may be equipped with a riser made of aluminum die-cast street. In addition, even when Step 12 having the above configuration is adopted for all steps, only a part of the steps can be obtained by attaching the display body 38 having no translucency to the back of the riser 19. Arbitrary measures such as displaying something are possible.
- an FRP riser having a predetermined translucency is used for the step of the escalator. It has design properties and can be used for various purposes.
