Description

  The present invention relates to a step illumination device for a passenger conveyor that illuminates a plurality of steps that circulate and move.

  In general, passenger conveyors such as escalators are connected to the entrance and exit provided at the landing, i.e., the entrance and exit, a plurality of steps that circulate and move to the sides of these steps. A railing that is erected, a handrail that is provided above the railing and that runs in synchronization with the steps, and a driving device that is provided below the entrance or exit and drives the steps and the handrail. Yes. When this drive device is driven, each step moves from the entrance to the exit with the tread surface directed upward.

  Passengers who use such passenger conveyors get on the treads of the steps that move away from the entrance side in time. The balance of the body may be lost by putting on or stepping off the tread.

  Especially for those who are not accustomed to using the passenger conveyor, even if you try to get on the step after grabbing the handrail, you do not know when to put your foot on the tread, so it takes time to get on the step from the entrance. It was a problem that the following passengers were crowded at the entrance. Therefore, in order to promote smooth use of the passenger conveyor, an apparatus for guiding the passenger to the step according to the movement of the step that circulates has been proposed.

  As one of the prior arts of this type of device, a generator that is disposed on a step and is driven by the rotational torque of a wheel of the step to generate electricity, and a battery that is disposed on the step and is charged by the power of the generator, In addition, there is known a step illumination device for a passenger conveyor that includes a lighting unit that emits light by supplying electric power from the battery and irradiates a tread surface from an irradiation window provided on the step (see, for example, Patent Document 1). In this step illumination device for a passenger conveyor, the passenger can grasp the speed of the step before entering the step by observing the movement of light emitted from the irradiation window of the step at the entrance.

  In addition to the step lighting device that displays the movement of the step by the light movement illuminated by the step, the step position for detecting the position of the step is a conventional technique for alerting passengers who enter the step. There is known an escalator illumination system including a detector, a light irradiation device that irradiates light on a tread surface of a step, and a light irradiation control device that irradiates light to the light irradiation device based on position information of the step (for example, , See Patent Document 2).

  Specifically, the light irradiation control device is an appropriate riding position on the tread when the step position detector detects that the entire tread surface of each step has been sent out from the landing floor. Light irradiation means for irradiating light to the standing position is provided, and this light irradiation means is installed, for example, on the ceiling of the hall or the surrounding structural wall. Therefore, the passenger can adjust the timing to the moving step by confirming the standing position on the tread illuminated by the light irradiating means from the ceiling part of the hall or the surrounding structural wall at the entrance.

  As another conventional technique, a balustrade transparent medium erected on the side of the step, for example, a light emitter disposed on the peripheral edge of the transparent panel, and a light emitter disposed on the surface of the transparent panel. 2. Description of the Related Art A passenger conveyor display device including a display object expressed by a photosensitive material that reacts with color is known (see, for example, Patent Document 3). According to this passenger conveyor display device, passengers do not step on the tread by confirming information such as characters displayed in response to light emitted from the illuminant guided through the transparent panel at the entrance. You can get on the steps with care for your feet.

  However, the conventional passenger conveyor step lighting device disclosed in Patent Document 1 described above has a generator and a battery mounted on each step in order to cause the lighting means of each step to emit light. In addition, it is necessary to periodically check the state of these generators and batteries, and the maintenance work for such generators and batteries is complicated. Furthermore, when each step that circulates and receives vibration, the vibration is transmitted to the generator and battery mounted on each step, which may adversely affect the power state of these generator and battery. In order to prevent this, it is conceivable to change the structure of each step to a structure in which vibration is not easily transmitted, but this is not preferable because the structure of the step after the change becomes complicated and the manufacturing cost of the step increases.

  Moreover, in the escalator illumination system of the prior art disclosed in Patent Document 2 described above, when there are many passengers using the passenger conveyor, the distance between the passengers before and after being lined up at the entrance is reduced, so the light irradiation means Even if the standing position on the tread is illuminated with light from the ceiling of the hall or the surrounding structural wall, this light is blocked by the passenger who got on the step first, and there is a concern that the following passenger can not confirm the standing position ing.

  Furthermore, in the display device of the conventional passenger conveyor disclosed in Patent Document 3 described above, even if information such as characters can be projected on the transparent panel of the balustrade, the transparent panel is on the side of the step, Since it is arranged along the traveling direction, there is a possibility that the information displayed when the passenger gets into the step from the entrance cannot be read. In particular, passengers who are not accustomed to using the passenger conveyor tend to watch the steps, so even if information such as characters projected on the transparent panel informs the timing of entering the steps, It is easy to overlook without noticing. As described above, the escalator lighting system and the passenger conveyor display device of the prior art have low convenience for passengers when getting on the steps, and even a passenger who is not used to using the passenger conveyor can get on the steps with peace of mind. Is desired.

  The present invention has been made based on the actual situation of the prior art as described above. The purpose of the present invention is to make it possible to easily perform maintenance work and improve the convenience for passengers when getting on the steps. The object is to provide a lighting device.

In order to achieve the above-described object, a step illumination device for a passenger conveyor according to the present invention includes a plurality of steps connected in an endless manner and circulated, and a skirt guard standing on the side of the plurality of steps. is applied to a passenger conveyor having a, in the step illumination device of a passenger conveyor which illuminate the footstep, provided in the skirt guard to face the footstep when moving in the horizontal direction, illuminating the footstep from the side The passenger conveyor includes a light source and a power supply device that supplies electric power to the light source, and the passenger conveyor includes a horizontally disposed entrance side horizontal portion and an exit side horizontal portion, and these entrance side horizontal portions and an exit side The step is provided on a surface facing the skirt guard, and a light receiving window for guiding the light illuminated from the light source to the inside; Led from window A light guide plate for receiving and emitting light with a light-emitting surface of the light guide plate and a viewing means provided visibly on the tread surface, the light source, the linearly in accordance with the trajectory in which the receiving window passes It consists of a plurality of LEDs arranged in the entrance side horizontal part and the exit side horizontal part, and the power supply device has flashing means for flashing a part of the light source facing the exit side horizontal part, This blinking means is configured by adding a blinking circuit capable of setting a time interval for blinking each of the plurality of LEDs arranged in parallel on the exit side horizontal part side by a timer relay.

  EMBODIMENT OF THE INVENTION Hereinafter, the form for implementing the step illuminating device of the passenger conveyor which concerns on this invention is demonstrated based on figures.

[First Embodiment]
The first embodiment of the stepped illumination device for passenger conveyors according to the present invention is endlessly connected to an entrance 21 and an exit (not shown) provided on the landing, that is, an entrance, as shown in FIG. The present invention is applied to a passenger conveyor that includes a plurality of steps 3 that circulate and move and a balustrade 10 that is disposed on the side of the plurality of steps 3.

  The passenger conveyor includes, for example, an escalator 20 installed in a building. The escalator 20 includes a horizontally disposed entrance side horizontal portion 15 and an exit side horizontal portion (not shown), and the entrance side. The horizontal part 15 and the lower part side horizontal part are connected, and it consists of the inclined part 16 arrange | positioned in the inclined form. In addition, in the escalator 20 according to the first embodiment of the present invention, the entrance 21 is set on the lower floor of the building, the exit is set on the upper floor of the building, and the step 3 is exited from the entrance 21, That is, it moves in the ascending direction and carries passengers.

  The balustrade 10 includes a skirt guard 6 erected on the side of the step 3, a transparent panel 11 extending upward from the skirt guard 6 and arranged along the direction of travel of the step 3, and the transparent panel 11. And a handrail 12 that is provided via a handrail guide (not shown) and travels in synchronization with the steps 3. The escalator 20 is provided below the entrance 21 or the exit, for example, below the exit, and includes a drive device (not shown) that drives the step 3 and the handrail 12.

  The step 3 described above includes a pair of front wheels (not shown) in which a chain (not shown) attached to the driving device is provided on the front shaft, and a pair of rear wheels 3a (FIG. 2) following these front wheels. The front wheel runs on a guide rail (not shown) extending along the skirt guard 6 and the step 3 is the entrance. It is designed to circulate between 21 and the exit.

  Accordingly, the step 3 appears from below the landing floor 21A of the entrance 21 with the tread surface facing upward, and travels in this order in the order of the entrance side horizontal portion 15, the inclined portion 16, and the exit side horizontal portion. Again, it is hidden under the landing floor at the exit (not shown). When a passenger who uses the escalator 20 stands on the landing floor 21 </ b> A of the entrance 21, the passenger rides on the tread surface of the step 3 that moves away from the entrance 21 in this manner.

  In the first embodiment of the present invention, the skirt guard 6 is provided so as to face the step 3 when moving in the horizontal direction, and includes a light source that illuminates the step 3 from the side. Consists of. The step 3 is provided on the surface facing the skirt guard 6 as shown in FIGS. 1 and 2, and the light receiving window 2 that guides the light illuminated from the LED 4 to the inside, and the light guided from the light receiving window 2. The light guide plate 1 that emits light upon receiving the light and the visual means 7 provided on the tread surface 3 so that the light emitting surface of the light guide plate 1 is visible.

  Specifically, the light guide plate 1 is formed in a rectangular parallelepiped plate shape, for example, in which the size of the light emitting surface is set to 1/2 or more of the tread surface. The size of the light receiving window 2 is set to be slightly larger than the size of the side surface of the light guide plate 1 so that the light guide plate 1 can be inserted into the step 3 from the side surface, for example. Further, the visual recognition means 7 is formed by, for example, assembling a frame constituting the tread surface of the step 3 in a lattice shape, and the light emitting surface of the light guide plate 1 can be viewed from the gap between the lattice-shaped frame members. . The frame of the tread is arranged in the central portion inside the outer frame when the light emitting surface of the light guide 1 is viewed from above, and is formed so as not to be biased back and forth in the traveling direction.

  Further, the skirt guard 6 is formed in a sheet shape or a thin plate shape as shown in FIG. 3, for example, and includes a pair of substrates 4 a on which the LEDs 4 are installed. The pair of substrates 4 a is the light receiving window 2 of the step 3. Is arranged in a line along the entrance side horizontal portion 15 and the exit side horizontal portion so as to face each other. The plurality of LEDs 4 of the skirt guard 6 are embedded in, for example, the substrate 4a in a state of being parallel to the entrance side horizontal portion 15 and the exit side horizontal portion, and the path through which the light receiving window 2 of the step 3 passes is embedded. They are arranged in a line.

  1st Embodiment of this invention is equipped with the power supply device 5 which supplies electric power to LED4, and this power supply device 5 is stored under the landing floor 21A, for example, so that it cannot be seen from the passenger on the landing floor 21A. And connected to the substrate 4a through the power line 5a. Therefore, when power is supplied from the power supply device 5 to the board 4a, each LED 4 on the board 4a is turned on.

  Thus, when the LED 4 is turned on, the light emitted from the LED 4 goes straight to the light receiving window 2 of the step 3. The light taken into the step 3 from the light receiving window 2 is diffusely reflected by the light emitting surface of the light guide plate 1 to emit light, and the light emitted from the light guide plate 1 passes through the gap of the grid frame of the step 3 to the step 3. It is designed to overflow to the outside.

  Moreover, the power supply device 5 has blinking means (not shown) for blinking a portion of the LED 4 that faces the horizontal part on the exit side. This blinking means is configured by adding a blinking circuit capable of setting a time interval for blinking each of the plurality of LEDs 4 arranged in parallel on the board 4a on the exit side horizontal portion by a timer relay, for example. For example, the LED 4 is set so that the LED that is closer to the exit of the LEDs 4 has a shorter blinking time interval.

  According to the first embodiment of the present invention configured as described above, the light guide plate 1 is fitted from the light receiving window 2, and the pair of substrates 4 a in which the plurality of LEDs 4 are embedded is provided on the skirt guard 6 to illuminate the step 3 from both sides. Accordingly, the light guide plate 1 itself does not directly receive power and emit light unlike a battery or the like, so that it is not necessary to check the state of the remaining power for each step 3. Even if a defect occurs in the light guide plate 1, the light guide plate 1 can be easily replaced by simply removing the light guide plate 1 from the light receiving window 2 and inserting a new one, so that maintenance work can be easily performed. In particular, since the light guide plate 1 does not need to consider the influence of the power state due to the vibration of the step 3 like a battery or the like, the structure of the step 3 can be simplified.

  Further, the step 3 guides light radiated from each LED 4 of the skirt guard 6 from the light receiving window 2 to the inside to cause the light guide plate 1 to emit light. Between the LED 4 and the light receiving window 2, a shield or the like is provided. Therefore, the optical path from the LED 4 to the light guide plate 1 can be reliably ensured. Therefore, regardless of the number of passengers, the passenger can check the light emitting surface of the light guide plate 1 from the gap between the grid-like frames of the steps 3. Accordingly, when the passenger stands on the landing floor 21A of the entrance 21, the movement of the step 3 is predicted in advance by following the light emitting surface of the light guide plate 1 of the step 3 traveling away from the landing floor 21A in front. This makes it easier to grasp the timing of getting into the step 3 from the movement of the step 3. Thus, since the convenience with respect to the passenger | crew at the time of boarding on the step 3 can be improved, while using the escalator 20 smoothly, the outstanding safety | security can be implement | achieved.

  Moreover, 1st Embodiment of this invention embeds several LED4 in the board | substrate 4a attached along the entrance side horizontal part 15 and the exit side horizontal part, and arrange | positions these LED4 to the light-receiving window of the step 3 2 is arranged in a line according to the trajectory through which 2 passes, so that even if the step 3 circulates, the light receiving window 2 of the step 3 and the LED 4 can face each other. Thereby, since the step 3 can take in the light illuminated from LED4 directly into the inside from the light-receiving window 2, the brightness | luminance which the light-guide plate 1 of the step 3 light-emits can be raised, and visibility can be improved. .

  Moreover, since 1st Embodiment of this invention uses LED4 as a light source, the electric energy which the power supply device 5 supplies can be restrained low, and energy saving can be implement | achieved. Furthermore, in the first embodiment of the present invention, the substrate 4a is formed in a sheet shape or a thin plate shape and integrated with the LED 4, so that the substrate 4a can be used even in a narrow place such as a gap between the skirt guard 6 and the step 3. Since it can be attached or attached, workability in maintenance work can be improved. Therefore, since it becomes easy to install the board | substrate 4a also on the passenger conveyor already installed in the building, a light emission function is changed by replacing the step of such a passenger conveyor with the step 3 which concerns on 1st Embodiment of this invention. It can be given later, and high versatility can be obtained.

  In the first embodiment of the present invention, the size of the light emitting surface of the light guide plate 1 is set to ½ or more of the area of the tread surface of the step 3, and most of the tread surface is a gap between the grid-like frame bodies. Therefore, an appropriate standing position on the tread surface of the step 3 can be indicated by the light emitting surface of the light guide plate 1. Therefore, since the place where a passenger steps on when stepping on the step 3 from the landing floor 21A can be quickly determined, the passenger can smoothly enter the step 3 and the transportation efficiency of the passenger can be improved. In particular, since the passenger can see the light emitting surface of the light guide 1 at the center of the tread of the step 3 in the traveling direction, the balance of the body can be maintained well even after riding on the tread without stepping off the tread. .

  Moreover, since 1st Embodiment of this invention is applied to the escalator 20 which connects an upper floor and a lower floor, the step 3 advances in order of the entrance side horizontal part 15, the inclination part 16, and the exit side horizontal part. Therefore, when the step 3 passes through the entrance-side horizontal portion 15, the light guide plate 1 is lit by receiving light from the LED 4 through the light receiving window 2, and when the step 3 passes through the inclined portion 16, the light guide plate 1 is turned on. Since the lights are turned off, it is possible to save extra power consumption when carrying passengers. And since the light guide plate 1 receives light from the LED 4 through the light receiving window 2 and blinks when the step 3 passes the exit side horizontal portion, the passenger waits for a while after the light guide plate 1 is turned off. By looking at the tread surface of the step 3 that emits light in front, it is possible to know that the exit is approaching, and it is possible to prevent crawling at the step between the landing floor and the step 3 without noticing the exit. Thus, since the passenger can prepare for getting off to the exit while riding on the step 3, the safety of the escalator 20 can be improved.

  In the first embodiment of the present invention, the power supply device 5 transmits power to the board 4a through the power supply line 5a and supplies power to each LED 4 on the board 4a. Can be turned on simultaneously, so that power can be distributed efficiently. Then, the power supply device 5 causes the LEDs 4 arranged in parallel on the board 4a on the exit side horizontal part side to blink by the blinking means, thereby introducing the step 3 when passing the exit side horizontal part as described above. Since the light plate 1 receives light from the LED 4 through the light receiving window 2 and blinks, it becomes easy to notice the light change of the light guide plate 1 corresponding to the lighting state of the LED 4 when the passenger gets down from the step 3 to the exit. Can attract attention.

  Further, in the first embodiment of the present invention, by setting the time interval for blinking the plurality of LEDs 4 arranged in parallel on the board 4a on the exit side horizontal portion by the timer relay to the LED 4 closer to the exit, The light guide plate 1 of the step 3 blinks rapidly as it approaches the exit, and then the step 3 is hidden under the landing floor of the exit and the light guide plate 1 is turned off, so that the passenger can be aware of the landing floor of the exit. It is possible to guide the passenger from the step 3 to the exit. In this way, the passenger can grasp not only the timing of getting into the step 3 from the entrance 21 but also the timing of getting down from the step 3 to the exit, thereby realizing excellent convenience.
