Abstract

PURPOSE:To form a passenger conveyer as a whole in good appearance excellent even in design by arranging, in the lower of a guard rail of a handrail, a light scattering plate forming a display surface having a pattern, character and a symbol or these combination. CONSTITUTION:A display device 10, formed by a graphic pattern, character and a symbol or these combined, is formed in a light scattering plate 9 mounted along the lengthwise direction under a handrail frame of a handrail 2. Thus, in addition to a function similar as in the past permeating illumination light from a source of light of fluorescent lamp or the like through the light scattering plate 9 illuminating the periphery of a staircase or the like, a display function is obtained by the display surface 10. Further, the display surface 10, in its graphic pattern, character, etc., can obtain illumination different from the other part in illumination intensity, color, etc., enabling the graphic pattern, character, etc., to be seen from a distant place, and the conventional monotonous illumination can be made excellent even in design having the display function with a passenger conveyer in good appearance as a whole.

Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a lighting device installed on the railing of a passenger conveyor such as an escalator or a moving handrail.

[Conventional technology]

Regarding Figures 9 to 11, for example, JP-A-62-28
A conventional lighting device for a passenger conveyor disclosed in Japanese Patent No. 5893 will be described. In Figure 9, 1 is the main frame of the passenger conveyor, 2 is the main frame 1
This is a parapet with three steps erected on both sides. Further, in FIGS. 9, 10, and 11, 4 is a balustrade panel made of a transparent plate, and 5 is a balustrade frame fixed to the peripheral edge of the balustrade panel 4 other than the underlined part through a packing. , there is a moving handrail 6 on the parapet frame 5.
A guardrail 7 supporting the parapet frame 5 is fixed, and the parapet frame 5
A plurality of light sources 8 made of fluorescent lamps are installed along the length of the balustrade frame 5 through holders (not shown) below the balustrade frame 5. The diffuser plate 9 is removably attached to the lower part of the camera along the longitudinal direction, and is made of milky white plastic. Next, the operation of the passenger conveyor illumination device configured as described above will be explained. By turning on the light R8, the illumination light emitted from these is diffused by the diffuser plate 9, brightly illuminating the steps 3 etc. through the balustrade panel 4, and the curve of the balustrade 2 is made to look beautiful from the outside of the passenger conveyor. .

[Problem to be solved by the invention]

Conventional lighting systems for passenger conveyors are constructed as described above, and the diffuser plate that surrounds the light source is made of plain milky white plastic, so there is a problem in that the lighting is monotonous and only functions to illuminate the surrounding area. Ta. The present invention solves the above-mentioned problems and provides a lighting device for a passenger conveyor that also has a display function, improves the appearance of the passenger conveyor as a whole including the handrail, and has an excellent design. The purpose is to

[Means to solve the problem]

The lighting device for a passenger conveyor according to the present invention has a display surface having a pattern, a character, a symbol, or a combination thereof formed on a diffuser plate disposed below a guardrail of a parapet.

[Operation] The lighting device for a passenger conveyor according to the present invention uses a diffuser plate to display an appropriately selected display surface containing excellent designs such as figures and patterns, letters such as advertisements, symbols including trademarks, and combinations thereof. In addition to the conventional function of illuminating the surroundings, such as steps, when the light source is turned on, the display screen can be used to display 81 functions, and the characters on the display screen can be illuminated with less illuminance than other parts. It can be illuminated in different colors, and the two characters on the display can be seen from a distance outside the passenger conveyor.

【Example】

Embodiments of the present invention will be described below with reference to the drawings. 1 to 3 show an embodiment of the present invention. In FIGS. 1, 2, and 3, FIG. The same symbols as in FIGS. 10 and 11 indicate corresponding parts, and 10
(The display surface 10 is printed on the inner surface of the diffuser plate 9 by silk screen printing, etc., and is formed on the outer surface of the diffuser plate 9, that is, the side opposite to the steps 3 and the lower surface near this side, and has characters. The remaining part is transparent or white, and the remaining part is opaque.If the text part is to be colored, the text part is printed with translucent paint.Also, the part other than the display surface 10 of the diffuser plate The display surface 10 is made of a milky white color similar to the conventional one so that the light illuminating the steps 3 can sufficiently pass through. The board 9 extends over almost its entire length along the longitudinal direction outside the inner board 4 of the balustrade frame 5,
The depth a near the entrance/exit is deeper than the depth b of the slope. Further, although not shown, the wiring of the light source 8 is provided in a part that cannot be seen from the outside, such as inside the guardrail 7. The configuration of this embodiment other than the above is the same as the conventional one shown in FIGS. 9 to 11. The lighting device for the passenger conveyor according to this embodiment is configured as described above, so that when the light source 9 is turned on, it not only illuminates the three steps as in the conventional case, but also brightly illuminates the text area with the display surface 10, allowing passengers to Can you add a display function that allows you to view from outside the conveyor? FIGS. 4 and 5 show other different embodiments of the present invention. The embodiment shown in FIG. 4 is different from the embodiment shown in FIGS. 1 to 3 in that the characters on the display surface 10 are changed and graphics are added to make the characters more noticeable. Also,
In the embodiment shown in FIG. 5, a pattern is printed on the display surface 10 to make the diffuser plate 9 more decorative. In the embodiment shown in FIG. 5, a display surface may be provided over the entire longitudinal direction of the balustrade. FIGS. 6, 7, and 8 show still other embodiments of the invention in which the light shielding means is changed. In the embodiment shown in FIG. 6, a display surface 10 is formed by printing on the entire outer surface of a diffuser plate 9 which has a groove-shaped cross section and is translucent, such as transparent. In addition, FIGS. 7 and 8 show the diffuser plate 9
A light-shielding plate 11 made of a stainless steel plate, a colored plastic plate, etc. is fixed to the inner and outer surfaces of the light-shielding plate 11, respectively, and by punching holes with two letters or the like in appropriate places on the light-shielding plate 11, a display surface through which light can pass can be created. It was formed. Note that the present invention is not limited to the above-mentioned embodiments, and a display surface may be formed by attaching a film or sheet to a light scattering plate and providing a pattern such as two letters that transmit light thereon. Range height. The length etc. can be changed in various ways, and the balustrade, light diffusion plate, and light source can also be changed as appropriate.

【Effect of the invention】

As explained above, according to the present invention, the pattern 2
Since the display surface consists of letters, symbols, or a combination of these, in addition to the conventional function of passing illumination light from a light source such as a warning light through the diffuser plate to illuminate the surrounding area, such as steps, the display surface can also be used for display purposes. In addition, the two characters on the display screen can be illuminated with different illuminance, two colors, etc. from other parts, and the two characters can be seen from a distance, replacing the conventional monotonous lighting. The present invention has the effect that the passenger conveyor as a whole has a good appearance and can be provided with an excellent illumination design.
