JPH0326694A - Getting on-off gate illuminating device for passenger conveyer - Google Patents

Abstract

PURPOSE:To prevent a light source unit from being stained and damaged while improving its safety by arranging the light source unit, which projects illuminating light from a meshing part between a footboard and a comb plate, in the reverse side of an on-off getting gate floor plate. CONSTITUTION:Lamp holders 7 are fixed to a tilt part in the vicinity of a supporting part of a comb plate 2 in the reverse side of an on-off getting gate floor plate 1, and a light source unit 8, consisting of fluorescent lamps or the like, is removably held to these holders 7. The light source unit 8 is arranged in a plural quantity so as to correspond to the total unit in a width direction of a footboard 3, and illuminating light 9, emitted from the light source unit 8, permeates through a clearance in a meshing part between the comb plate 2 and the footboard 3 so as to illuminate a central side in the lengthwise direction of a passenger conveyer. Consequently, a boundary part between the footboard 3 and the comb plate 2 is clearly lighted, and the safety of passengers is improved. And, because the light source unit 8 is arranged on the reverse side of the on-off getting gate floor plate 1, the light source unit 8 is prevented from being stained by such as a tread with a footgear of the passenger and so damaged as by a thrust with the point of an umbrella, accordingly the intensity of illumination of the illuminating light is prevented from easily deteriorating.

Description

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

The present invention relates to an entrance lighting device for a passenger conveyor such as an escalator or a moving passage.

[Conventional technology]

Conventionally, as a passenger conveyor entrance illumination device as described above, there has been one disclosed in Japanese Utility Model Application Laid-Open No. 63-73280. This boarding/exit lighting device is installed on the surface side between a comb plate that is placed at the boarding/exit area and engages with the steps to scoop up passengers' feet, and the boarding/exit floorboard (I board base) to which this comb board is fixed. A light source such as a lamp was buried in the area. This boarding/exit lighting device illuminates the light source to make passengers aware of the engagement portion between the tread and the comb board, thereby preventing the danger of passengers getting on and off the tread from falling. Ta. And this entrance lighting device is
The surface between the comb plate and the floorboard of the entrance/exit was illuminated by a light source.

[Problem to be solved by the invention]

Conventional passenger conveyor boarding/exit lighting devices are constructed as described above, and emit light from the surface between the comb plate and the boarding/exit floorboard, so that the surface of the comb plate is on the side where it engages with the tread. Because the comb plate and the tread plate are slanted downward, the illumination light is not sufficiently irradiated onto the boundary between the comb plate and the tread plate and is diffused upward. To be clear, the light-emitting surface between the comb board and the boarding/exit floorboard may become dirty with mud or water from being stepped on by passengers' footwear, or may be damaged by being poked by the tip of an umbrella. There has been a problem in that the illumination intensity of the illumination light emitted from the light source is reduced. This invention was made to solve the above-mentioned problems, and allows passengers to clearly recognize the boundary where the tread and the comb board engage, improving safety. It is an object of the present invention to provide a lighting device for an entrance/exit for a passenger conveyor, which prevents the body from getting dirty or damaged and whose illuminance does not easily decrease.

[Means to solve the problem]

In the passenger conveyor entrance illumination device according to the present invention, a light source body that emits illumination light from between the engagement portion of the tread and the comb board is disposed on the back side of the entrance/exit floorboard.

[Effect]

In the entrance lighting device according to the present invention, light emitted from a light source such as a fluorescent lamp is emitted from between the engagement portion between the tread and the comb plate toward the longitudinal center of the passenger conveyor.
The boundary between the tread plate and the comb plate is clearer than the conventional one. Furthermore, since the light source is disposed on the back side of the floorboard of the entrance/exit, the light source is not stepped on by passengers' footwear or poked by the tip of an umbrella, and is less likely to get dirty or damaged.

【Example】

An embodiment of the present invention will be described below with reference to the drawings. In Figures 1 and 2, reference numeral 1 denotes the floorboard of the entrance/exit, 2 a comb plate fixed to the floorboard 1 of the entrance/exit, and 3 a number of steps connected in an endless manner that circulate in the longitudinal direction of the passenger conveyor. These tread plates 3 have a large number of uneven grooves formed on their surfaces, and these are configured to mesh with the comb teeth of the comb plate 2. Further, 4 is a movable handrail supported by the parapets erected on both sides of the steps and driven in synchronization with the steps, 5 and 6 are inner decks and outer decks arranged on both sides of the lower part of the side panels of the balustrades, The above configuration is the same as that of a normal escalator. In this embodiment, as shown in FIG. 1, lamp holders 7 are fixed to an inclined part of the back surface of the entrance/exit floor plate 1 near the support part of the comb plate 2, and a light source body 8 made of a fluorescent lamp or the like is attached to and detached from these holders 7. Possibly held. A plurality of light source bodies 8 are arranged so as to correspond to the entire width direction of the footboard 3.
The illumination light 9 emitted from the comb plate 2 passes through the gap between the engagement portion of the comb plate 2 and the tread plate 3 and illuminates the center side in the longitudinal direction of the passenger conveyor. Although not shown in the drawings, it is preferable to provide a reflecting plate for giving directionality to the illumination light from above near the light source body to both ends of the passenger conveyor. In addition, although the above-mentioned embodiment described an escalator entrance/exit illumination device, the present invention can also be applied to a passenger conveyor such as a moving passageway in which pallet-shaped treads are connected endlessly.

【Effect of the invention】

As explained above, according to the present invention, illumination light is emitted from between the engagement portion between the tread and the comb plate fixed to the entrance/exit floor board by the light source disposed on the back side of the entrance/exit floor board. Therefore, the boundary between the tread and the comb board is clearer than in the past, and the boundary can be clearly recognized by passengers, improving passenger safety. The light source is located on the back side of the floorboard of the entrance and exit, and the light source does not get dirty due to being stepped on by passengers' footwear or gets damaged due to being poked by the tip of an umbrella. This has the effect of providing a passenger conveyor entrance/exit lighting device in which the illuminance of the passenger conveyor is unlikely to decrease.
