DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a passenger conveyor such as an escalator and an electric road, and more particularly to a passenger conveyor provided with a balustrade lighting on a balustrade.

[0002]

2. Description of the Related Art Illumination of a balustrade of a passenger conveyor is generally performed by using an illumination lamp as disclosed in Japanese Patent Application Laid-Open No. H11-255458 or using an optical fiber as disclosed in Japanese Patent Application Laid-Open No. 61-174090. The ones used are known.

[0003]

In each of the above prior arts, since a lamp is used as a light source, there is a problem that the lamp burns out and a large number of wirings connected to the lamp are required.

[0004] It is an object of the present invention to provide a passenger conveyor that does not have to worry about running out of lamps in balustrade lighting.

Another object of the present invention is to provide a passenger conveyor having a small number of wires to a balustrade lighting.

[0006]

According to the present invention, in order to achieve the above object, a voltage is applied between electrodes sandwiching a light emitting layer,
The balustrade illumination was constituted by a light emitting means for causing the light emitting layer to emit light by a potential difference.

The balustrade lighting by the above-mentioned light-emitting means does not use a lamp for lighting or a light source lamp of an optical fiber, so that there is no lamp cut-off and lamp replacement accompanying it, and a light-emitting means formed linearly as balustrade lighting. By using, the wiring may be connected to the end of the linear light emitting means, so that the number of wirings can be reduced as compared with the conventional balustrade lighting wired for each lamp.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment according to the present invention will be described below with reference to FIGS. An escalator 1, which is a kind of a passenger conveyor, includes a frame 2 installed over upper and lower floors, a plurality of steps 3 connected endlessly within the frame 2 and circulating, and a moving direction of the steps 3. It has a pair of balustrades 4 erected along both sides, and a moving handrail 5 guided by the periphery of the balustrade 4 and driven in synchronization with the steps 3.

The balustrade 4 is fixed to the frame 2 by fixing members 6 and 7.
, A handrail guide 9 fixed to the periphery of the glass panel 8 for slidingly guiding the moving handrail 5, and an inner deck cover for covering the inside of the lower end of the glass panel 8 10 and the inner deck cover 10
And a skirt guard 11 for separating the steps 3 from each other, and an outer deck cover 12 for covering the outside of the lower end of the glass panel 8. Note that an exterior plate 13 is vertically disposed so as to be continuous with the end of the outer deck cover 12. The glass panel 8 can be formed using a single tempered glass plate over the entire length of the balustrade 4, but generally, a plurality of divided tempered glass plates are connected in a row.

In the escalator 1 having the above structure, a balustrade illumination 14 is generally provided on the balustrade 4 in order to brighten an area used by passengers. This balustrade lighting 14
Is mounted along a moving handrail 5 around the balustrade 4.

The balustrade illumination 14 according to the present embodiment is adhered to the lower surface of the handrail guide 9 with an adhesive 15 inside the glass panel 8 (on the side of the steps 3). As shown in FIG. 3, the balustrade illumination 14 is formed in a cylindrical shape by covering a first electrode 16 made of a core wire such as a copper wire and a light-emitting material such as phosphor on the outer periphery of the first electrode 16. Light emitting layer 17
And a first transparent insulating layer 18 covering the outer periphery of the light emitting layer 17.
A second electrode 19 having a wire wound around the outer periphery of the first transparent insulating layer 18 in a net shape; and a second transparent insulating layer 20 covering the outer periphery of the second electrode 19. The electroluminescent means has an outer periphery covered with a transparent protective body 21.
The transparent protective body 21 is attached to the handrail guide 9 by the adhesive 15.
The balustrade lighting 14 along the handrail 5
Will be attached.

The first electrode 16 and the second electrode 16
The electrodes 19 are connected to lead wires 22a and 22b, and the lead wires 22a and 22b are connected to the inverter device 23.
The inverter device 23 is connected to a power supply unit (not shown) provided in the frame 2 of the escalator 1 via a power converter 24 and lead wires 25a and 25b. Here, the inverter device 23 and the power supply converter 24 are a power supply device for causing the electroluminescent device to emit light, and are installed in the frame 2.

Since the balustrade lighting 14 is formed in a linear shape, both ends thereof face the inside of the inner deck cover 10 or the inside of the frame 2 inside the outer deck cover 11 from near the entrance of the moving handrail 5. From there, lead wires 25a, 25
Since the wiring is performed by b, no wiring is required around the balustrade illumination 14. Also, the number of wires in the frame 2 is basically 2
Since it is a book, wiring space is hardly needed.

When lighting is performed by the lighting device 14 having the above-described configuration, first, the lead wires 25a and 25b are connected to a power supply section of, for example, 100 VAC in the frame 2 directly or via a switch or the like. AC 1 by connecting to power supply
00 volts is stepped down to 12 volts DC and converted to DC by the power supply converter 24, and
It is boosted and frequency converted to 200 volts at 0 Hz. When this AC voltage is applied to the first electrode 16 and the second electrode 19 via the lead wires 22a and 22b, the first electrode 1
A potential difference occurs between the first electrode 16 and the first transparent insulating layer 18, and this potential difference causes the light emitting layer 17 sandwiched between the first electrode 16 and the second electrode 19 to emit light. This light is applied to the first transparent insulating layer 1
8. The vicinity of the balustrade 4 is illuminated through the second transparent insulating layer 20 and the transparent protective body 21.

As described above, according to the present embodiment, since no lamp is used as the light source of the balustrade illumination 14, there is no lamp burnout and there is no problem such as lamp replacement. further,
Since no lamps are used, the number of wirings required by the number of lamps can be eliminated, and problems such as securing a wiring space are eliminated.

In the above embodiment, the moving handrail 5 is used.
Although the balustrade illumination 14 is adhered to the handrail guide 9 along the line, this does not prevent attachment to the handrail guide 9 by well-known fixing means. Also, without attaching the balustrade illumination 14 to the handrail guide 9, as shown by a two-dot chain line in FIG.
The balustrade lighting 14a may be directly attached to the glass panel 8 by bonding or the like. Further, when the illuminance is low, 2 in FIG.
As indicated by the dashed line, the two balustrade lights 14a and 14b may be provided side by side.

In the above description, the entire area used by the passengers of the escalator 1 is uniformly brightened. However, since the balustrade lights 14, 14a and 14b do not change, the passengers approach the exit. Sometimes it doesn't get there. That is, when the escalator 1 is used alone, it can be recognized that the exit is close due to changes in the surrounding buildings. However, when using it as a group, you will not be able to know that the exit is close when you are absorbed in talking and do not arrive at changes in the surrounding buildings and when the front of the direction of travel is blocked by other passengers There is a danger.

For this purpose, according to another embodiment of the present invention shown in FIG. 4, the balustrade illumination is divided into three parts: the inclined straight section A, the lower end B, and the upper end C of the balustrade 4. The balustrade lights 14 and 14C with different emission colors were installed to call attention. That is, the emission color of the balustrade illumination 14C in the vicinity of the vehicle entrance / exit portion is set to, for example, a reddish color that has a more alert effect than the emission color of the balustrade illumination 14 in the middle part.

As described above, even if the front end in the traveling direction is not visible by changing the emission color, or even if the front end in the traveling direction is not visible, the emission color of the balustrade changes to recognize that the exit is near. be able to.

It is to be noted that a green light emission color is used on the entrance side, natural light is used in the middle part, and a red light emission color is used near the exit.
At the time of boarding, the passenger can be calmed down and the passenger is notified that the exit is approaching, so that the passenger can get on and off the vehicle more smoothly.

The balustrade lights 14 and 14C are provided with moving handrails 5.
However, when it is desired to further emphasize the approach of the exit, as shown by a two-dot chain line, the inclined straight line portion A side of the balustrade lighting 14C is adjacent to the tempered glass plate 8 adjacent thereto.
By passing between A and 8B and between 8A and 8C, the balustrade lights 14 and 14C are arranged so as to surround the glass plates 8B and 8C.
Can be emphasized.

According to the above-described embodiment using the balustrade lights 14 and 14C having different emission colors, the lead wires of the balustrade lighting 14 and the balustrade lighting 14C are led out differently. That is, balustrade lighting
Since the end of 14C faces the inside of the inner / outer deck cover from the vicinity of the entrances 5A and 5B of the moving handrail 5, lead wires can be drawn out from there to the power supply unit in the frame. However, since the end of the balustrade illumination 14 located in the middle of the two balustrade illuminations 14C is located above the glass panel 8A, it is not possible to draw out a lead wire therefrom to a power supply in the frame. For this reason, the lead wire of the balustrade illumination 14 is drawn out from the groove 9 formed at the top from the balustrade illumination 14 side of the handrail guide 9 shown in FIG.
A small hole may be made to penetrate into S, and a lead wire may be routed using the concave groove 9S to connect the vicinity of the entrances 5A and 5B of the moving handrail 5 to a power supply unit in the frame. Alternatively, as shown in FIG. 1, the upper end 8T of the glass panel 8 and the glass panel 8
Can be used for drawing out the lead wire.

In addition, the transparent protective body 21 of the balustrade lighting 14
As shown in FIG. 5, a groove 21G is formed on the side of the mounting surface 21S to which an adhesive or the like is applied.
If the lead wires 22a and 22b are routed in the G, it is not necessary to specially process the handrail guide 9 and the like.
When using the transparent protective body 21 shown in FIG.
The lead wires 22a, 22
It is more convenient to provide coloring or a shield so that the presence of b is not known.

In the above description, light reaches around the balustrade 14 in order to brighten the area used by passengers. Some of them illuminate the parapet. One example will be described with reference to FIG.

In FIG. 6, the structure is almost the same as in FIGS. 1 to 3, and the same parts are denoted by the same reference numerals. The upper end of the glass panel 8 is inserted into the concave groove 9G of the handrail guide 9, and the lower end of the glass panel 8 is inserted into the concave groove 7G of the fixture 7 fixed to the frame 2. . A balustrade illumination 2 composed of electroluminescent means using these concave grooves 7G and 9G.
6 is attached. Specifically, between the upper end 8T of the glass panel 8 and the bottom of the concave groove 9G, a balustrade illumination 26 having the same configuration as the above-mentioned electroluminescent means is installed, and the lower end 8B of the glass panel 8 and the concave groove 7G are provided. The light reflecting member 27 is provided between the light reflecting member 27 and the bottom.

With the above configuration, the light due to the electroluminescence proceeds downward along the glass panel 8, and the light is reflected upward by the light reflector 27. At this time, the light reflecting material 27
The light reflection direction can be changed in various ways by inclining the panel, providing a curved surface or an inclined surface, and reversing the installation positions of the balustrade illumination 26 and the light reflecting material 27.

The illumination by the combination of the balustrade illumination 26 and the light reflection material 27 brightens a limited area of the glass panel 8 and is an illumination that can improve the design effect.

In the above embodiment, as the balustrade 4, a glass panel 8 with an emphasis on design is used. However, escalators used in stations, public facilities, etc., place more emphasis on practicality than design. It has a balustrade. The balustrade lighting applied to the balustrade configuration emphasizing this practicality will be described below with reference to FIGS. 7 and 8.

The balustrade 30 shown here comprises a plurality of columns 31 erected at appropriate intervals in the longitudinal direction of the frame 2 and handrails supported on the upper ends of these columns 31 along the longitudinal direction of the frame 2. Frame 32 and the inside of this handrail frame 32 (step 3 side)
An inner panel 34 made of, for example, a stainless steel plate hanging down from the inner panel 34, an inner deck cover 10 covering a lower end portion of the inner panel 34, a skirt guard 11 for separating the inner deck cover 10 from the steps 3, and the handrail frame 32. And an exterior plate 35 hanging down from the outside.
Note that a handrail guide 33 is mounted on the handrail frame 32 to guide the moving handrail 5.

The balustrade lighting of the balustrade 30 configured as described above is not an original lighting that requires brightness, but a warning light for calling for safety and attention. Therefore, it is not necessary to provide a lighting device over the entire area of the balustrade 30, for example, in order to inform passengers that the exit is near, an illumination hole 34H is opened circularly in the inner panel 34 near the entrance / exit,
On the back side of the illumination hole 34H, the balustrade illumination 14 composed of the electroluminescent means is installed in a circular shape by the holding means 36.

Further, in order to emphasize the boundary between the floor 37 and the step 3, and to ensure the safety of getting on and off, the illumination holes 10H and 1H are provided near the boundaries of the inner deck cover 10 and the scard guard 11.
1H is provided, and balustrade illuminations 14A and 14B composed of electroluminescent means are arranged behind these illumination holes 10H and 11H. In particular, when attention is required at the foot, a plurality of electroluminescent means may be arranged as the balustrade illumination 14B.

Further, the illumination holes 10H, 11H, 34
H may be provided independently or in combination. When the illumination holes 10H, 11H, and 34H are provided in combination, effective alerting can be performed by changing the respective emission colors.

Since the lamp is not used by the above-mentioned stimulating illumination, there is no fear of running out of the lamp, and a large number of wirings are not required.

In each of the embodiments described above, the balustrade lighting 14 (14a, 14b, 14A to 14C,
Each of 26) has a single kind of light-emitting layer, and thus emits a single color. On the other hand, one balustrade lighting 1
4 (14a, 14b, 14A to 14C, 26), when it is desired to emit a plurality of colors, this can be achieved by alternately providing a plurality of types of light emitting layers in the longitudinal direction.

However, the range of light emission is not determined by the application location, and if it is desired to apply the light emission to such a location immediately, the light emitting layer cannot be attached or detached, which may be difficult to cope with.
In such a case, a configuration as shown in FIG. 9 can easily obtain a plurality of emission colors.

That is, in FIG. 9, a balustrade lighting 14 which emits natural light is used, and a plurality of transparent protecting bodies 21A to 2A, each of which is colored in a different color, is used to cover them.
1C. Then, the transparent protective bodies 21A to 21A
By selecting the color and length of C according to the application location, it is possible to emit the required color at the required location.

When the colored transparent protective bodies 21A to 21C are used, the boundary between the different color light emitting portions becomes clear, and depending on the application place, it may be desired to change the boundary between the different color light emitting portions so as not to be conspicuous.

In such a case, as shown in FIG. 10, balustrade illuminations 40 and 41 having different emission colors are used, and the balustrade illuminations 40 and 41 having the standard length are used.
A, 41A, parapet lighting 40 extended to the other side
If the balustrades B, 41B and the balustrades 40C, 41C shorter than the balustrades 40A, 41A of the standard length are arranged side by side, the luminescent color gradually changes at the portion where the different color light emitting portions overlap each other.

In each of the above embodiments, for example, as shown in FIG. 3, the entire periphery of the balustrade illumination 14 is covered with a transparent protective body 21 having a square cross section. However, the present invention is limited to this kind of transparent protective body 21. Instead, for example, a concave groove may be formed in the transparent protective body 21 having various square cross sections, and the balustrade illumination 14 may be inserted and held in the concave groove, or the cross section may be circular.

Each of the above embodiments is an example of application to a newly-installed escalator, but the balustrade illumination of an existing escalator can be changed to balustrade illumination by electroluminescent means by modification. That is, in the balustrade illumination shown in FIG. 11, a handrail guide frame 50 for guiding the movement of the moving handrail 5 is fixed to the upper end of the glass panel 8, and this handrail guide frame 50 is attached to the glass panel 8.
A lower frame 51 having a fixing portion 53 of an inverted U-shaped groove for fixing to the handrail, and an upper frame 52 having a U-shaped cross section that supports the handrail guide 33 of the moving handrail 5 are provided. Conventionally, a balustrade such as a fluorescent lamp is installed using the space of the lower frame 51 and is covered with a light-transmissive illumination cover 54. However, according to the present embodiment, a fluorescent lamp or a fluorescent lamp is used. The necessary equipment and wiring were removed, and the balustrade lighting 55 in which a plurality of the aforementioned linear electroluminescent means were bundled was installed. still,
In the drawing, reference numeral 56 denotes a light reflecting plate.

As described above, the balustrade lighting by the electroluminescent means can be easily installed in place of the existing balustrade lighting.

In the above embodiments, the escalator has been described as a passenger conveyor. However, it is needless to say that the present invention can be applied to an electric road having no step between adjacent steps or steps.

[0043]

As described above, according to the present invention, it is possible to obtain a passenger conveyor having no bamboo lighting lamps and a small number of balustrade wirings.
