Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention is directed to a wheelchair passenger, etc., which can be used safely and securely not only by general passengers but also by special passengers who use wheelchairs, strollers, shopping carts, etc. It concerns type escalators.

[Conventional technology]

Since the purpose of conventional escalators is to transport general passengers, the depth of the steps is approximately 400 mm.
It has become a degree. Therefore, due to the size, it has been difficult to safely transport wheelchairs, strollers, etc. while keeping them in a horizontal state.

For this reason, for example, as disclosed in Japanese Patent Publication No. 56-41555, one or more large steps with sufficient depth to safely transport a wheelchair while keeping it in a horizontal position are installed in advance, and the A dedicated passenger conveyor start/stop switch is installed at the entrance, and when the stop switch is operated, this large step is always stopped at the entrance, and the dedicated start switch is pressed after a wheelchair passenger gets on board. This will cause the escalator to start, and after a certain period of time, the large steps will stop again at the exit of the destination floor.

For example, as disclosed in Japanese Patent Publication No. 58-2153, an escalator with a substantially large depth that can carry vehicles is constructed by connecting all the steps by pivoting the main tread and the auxiliary tread. What constitutes.

Various proposals have been made.

However, escalators like the former are always equipped with large steps with a depth that is deep enough for wheelchairs, etc., even if there is only a limited number of steps among the multiple steps. The radius of the chain gear device, etc. for the reversing drive must be increased, and the escalator body that accommodates this inevitably becomes large, which limits the installation space. The riser dimension of the steps is also larger than that of a normal step, and there is a risk that passengers may trip. Also, because the large steps are mixed together irregularly, it is difficult to know when to reach the entrance.
When boarding a wheelchair or the like, it is necessary to detect large steps and temporarily stop the steps at the entrance, which poses the problem of blocking the flow of traffic each time.

On the other hand, in the case of escalators like the latter,
Unlike the former case, the radius of the chain gear device for reversing the vehicle at the entrance/exit does not become large, but it is possible to construct a large step with a depth that allows a large wheelchair to ride on it. If you try to maintain a maximum inclination angle of 30° like an escalator,
The riser height of the steps becomes too high, creating the risk of tripping when passengers move on the steps.If an attempt was made to keep the riser height of the steps to about 200mm, which is the same as on conventional escalators, The maximum inclination angle is reduced to about 10°, and in order to obtain the necessary lift, the overall length of the escalator inevitably becomes longer and the installation area increases significantly.

For this reason, applicants have recently, for example,
As stated in No. 160448, we are proposing escalators that have appropriate riser heights and maximum inclination angles, can transport general passengers and vehicles at the same time without the risk of becoming too large.

In this method, a large step with a wide depth is constructed by continuously arranging a plurality of specific steps each having a predetermined depth, and a predetermined number of general passenger steps each having a predetermined depth are continuously arranged between the large steps. The large step and the general passenger step are arranged to form one unit step, and the unit step is connected endlessly by a drive chain, and the number of the general passenger step arranged is changed. This allows the maximum inclination angle of escalators, etc. to be changed arbitrarily.

The latest tiltable escalator and the like will be described below with reference to the drawings.

Fig. 2 is a side view showing an example of the lower floor portion of this tiltable escalator, Fig. 3 is a detailed view showing an example of the configuration of the step shown in Fig. 2, and Fig. 4 is a side view showing an example of the lower floor portion of this tiltable escalator. This is an explanatory diagram for explaining the basic technical concept. In the diagram, 1 is the escalator body, 2 is the handrail, and 3 and 4 are the risers 3a.
and 4a, and 10 is a large step for transporting wheelchairs while keeping the three specific steps 11, 12, and 13 (described later) always in the same horizontal state during the transport section. and the general passenger steps 3 and 4 (it may be only the general passenger steps 3 or 4, or there may be a large number of general passenger steps 3 and 4), forming one unit step 100. As with conventional steps, the steps 3 and 4 for general passengers have front wheels 31 and 41 located below the front end and below the rear end.
and rear wheels 32, 42 are rotatably provided, and in the maximum inclination section, the front wheels 31, 41 and the rear wheels 32, 42 are supported and guided by guide rails 33, 43, 34, 44 having a predetermined inclination angle θ. be done.
The specific step 11 has the same structure as the general passenger steps 3 and 4, and has a riser 11a, and a front wheel 111 and a rear wheel 112 are rotatably provided at the lower front end and the lower rear end. and rear wheel 11
2 is supported and guided by guide rails 113 and 114 having a predetermined inclination angle θ in the maximum inclination section of the escalator. On the other hand, specific steps 12 and 13
Both have the same structure as the general passenger step except that they do not have a riser part (they may also be general passenger steps with a riser part), but there are front wheels 121 and 131 at the lower front end and the lower rear end, respectively. Rear wheels 122, 132 are rotatably provided, and the front wheels 121, 131 and the rear wheels 122, 132 also have guide rails 123, 133, respectively, which have predetermined inclination angles θ in the maximum inclination section of the escalator.
It is supported and guided by guide rails 124 and 134, but only the guide rail 133 has a U-shaped cross section to prevent the specific step 13 from floating upward. The drive chain 20 for driving the steps is, for example, a shaft 31a, 4 of the front wheels 31, 41 of the steps 3, 4 for general passengers, as shown in FIG.
1a and the front wheel 11 of specific steps 11, 12, 13
1, 121, 131 axes 111a, 121a, 1
31a and are connected endlessly.

Incidentally, as shown in FIG. 5, the riser of an escalator step usually draws a curved line having a constant radius R, that is, the depth dimension L of the tread 5, centered on the front end A5 of the tread 5 of the step. From this, the maximum inclination angle θ of the escalator that constitutes the unit step 100, in which the large steps and normal steps shown in FIG. 3 are regularly mixed, is determined.
As shown in Fig. 4, n is the number of general passenger steps per unit step, H is the common riser height of the steps, L is the depth dimension of the general passenger steps, and is the inclination of the general passenger steps. If the angle is θ ₁ and the depth dimension magnification of the large step with respect to the general passenger step is N, then θ = tan ^-1 H (n + 1) / L (N - 1) + L (n + 1) cos θ ₁
It can be expressed as...

That is, in FIG. 3, for example, the depth L of the steps 3 and 4 for general passengers is 400 mm, the riser height H of the steps is 200 mm, the depth dimension magnification N of the large step 10 is 3, and the slope of the steps 3 and 4 for general passengers is If the angle θ ₁ is 30°, the maximum inclination angle θ of the escalator in Fig. 3 is one unit step 10.
It is expressed as a function regarding the number n of general passenger steps 3 and 4 in 0, and as long as N is K>1, n
It can be seen that the larger the number, the larger the value θ in the equation, which means that the maximum inclination angle θ can be made as large as necessary without changing the riser dimension H of the step.
Therefore, if the escalator is configured as shown in Figure 3, in order to secure the required lift height, the maximum inclination angle can be set to the riser of the steps, even though there are large steps that can accommodate wheelchairs, etc. Since the escalator can be made larger without increasing the height, it is possible to obtain an escalator with a short overall length. Furthermore, since the riser height of the large steps and the riser height of the steps for general passengers are the same, even when passengers move on the unit steps, there is little risk of tripping and it is safe.

In the configuration shown in FIG. 3, the number of guide rails for guiding the front and rear wheels of each step increases, but in order to alleviate this problem, the configuration of the steps shown in FIGS. 6 and 7 may be adopted.

First, in FIG. 6, the same reference numerals as in FIG. This large step 5 is a large step that can be bent but is connected so that it does not bend toward the surface side, and is always kept in the same horizontal state during the conveyance section.
0 and general passenger steps 3 and 4 (in this case, there may be only general passenger steps 3 or 4, or there may be multiple general passenger steps 3 and 4) as shown in Fig. 3. Similarly, one unit step 200 is constructed. Specific step 51
, has a riser 51a similar to the steps 3 and 4 for general passengers, and a rear wheel 512 is rotatably provided below the rear end (no front wheel is provided at the front end). is supported and guided by a guide rail 514 having a predetermined inclination angle θ in the maximum inclination section. Next, specific step 5
2 has only a tread 52b, the specific step 53 also does not have a riser, and a front wheel 531 is rotatably provided below the front end (no rear wheel is provided at the rear end). It is supported and guided by a guide rail 533 having a U-shaped cross section and having a predetermined inclination angle θ in the maximum inclination section. Therefore, in the configuration shown in FIG. 6, the number of guide rails on one side is four fewer than in the configuration shown in FIG. 3. The drive chain 21 for driving the steps includes the shafts 31a, 41a of the front wheels 31, 41 of the general passenger steps 3, 4, and the shafts 31a, 41a of the front wheels 31, 41 of the general passenger steps 3, 4,
It is attached to the shaft 531a of the front wheel 531 of No. 3 and connected endlessly. The riser 51a of the specific step 51 differs from the riser 11a of the specific step 11 shown in FIG. 3 as follows.

That is, the general passenger step 3 facing the riser 51a of the specific step 51 shown in FIG.
1 axis 531a and the front wheel 3 of the general passenger step 3
1, the riser 51a of the specific step ₅₁ must be configured to draw a curved surface with this distance _R1 as its radius, but as shown in FIG. Specific step 1
1, riser 1 of this particular step 11
1a is the shaft 111 of the front wheel 111 of the specific step 11
a and the shaft 31a of the front wheel 31 of the general passenger step 3.
The radius may be the same as the curved surface of the risers 3a and 4a of the steps 3 and 4 for general passengers.

Now, in the unit step 200 of FIG. 6, for example, the front end A3 of the general passenger step 3 is
and the front end A5 of the rear wheel shaft 31a and the specific step 53.
3 and the front wheel 531a form a parallelogram, the riser 51 of the specific step 51
A must form a curved surface having a radius equal to the depth dimension _R2 of the large step 50, with the front end A53 of the specific step 53 being stopped. This dimension R ₁ matches the dimension R ₂ in size.

Next, an embodiment in which the number of guide rails can be further reduced by two on one side will be described with reference to FIG. 7. In FIG. 7, 60 indicates specific steps 61 and 6.
A large step 612 is connected to the riser 61a by means of hinges 64 and 65, for example, so that it can bend only toward the back side at the opposite end surfaces of the steps 2 and 63, and is always kept in the same horizontal state during the transport section of people or vehicles. A rear wheel rotatably provided below the rear end of a specific step 61 having a
2 is supported and guided by a guide rail 614 having a predetermined inclination angle θ in the maximum inclination section of the escalator.

631 is a shaft 63 located below the front end of the specific step 63.
The front wheel 631 is rotatably provided through the escalator 1a, and is supported and guided by a guide rail 633 having a predetermined inclination angle θ in the maximum inclination section of the escalator. 66 is a specific step 61, 62
This is a support link that rotatably connects the lower front ends of the wheels with pins 66a and 66b and also rotatably connects with the front wheel shaft 631a of the specific step 63. In this case, the link is bent only toward the tread surface side of the large step 60. For example, hinge 66
c, 66d. 7 and 8 are riser 7a,
8a, and 72 is a rear wheel rotatably provided below the rear end of the general passenger step 7. It is supported and guided by rails 74. Reference numeral 82 denotes a rear wheel rotatably provided below the rear end of the step 8 for general passengers, and this rear wheel 82 is also connected to the guide rail 8 having a predetermined inclination angle θ in the maximum inclination section of the escalator.
4 is supported and guided. Reference numeral 67 rotatably connects the lower front ends of the steps 7 and 8 for general passengers to the support ring 66 by pins 67a and 67b, and the lower front end of the specific step 61 above the step 7 for general passengers to the support ring 66 using the aforementioned pin 66a. At the same time, the shaft 631' of the front wheel 631' of the specific step 63' that constitutes the large step below the general passenger step 8
a is a support link slidably connected via an elongated hole 67c, between pins 67a and 67b;
7a and pin 66a and between pin 67b and shaft 63
1'a, for example, hinges 67d, 67e,
The link pieces are connected at 67f. This large step 60 and general passenger steps 7 and 8
(There may be only one step 7 or 8 for general passengers, or there may be many steps 7 and 8 for general passengers.) One unit step 300
The drive chain 22 for driving this unit step 300 includes specific steps 63,
63' front wheels 631, 631' axles 631a, 63
It is attached only to 1'a and is connected endlessly.

Now, for example, specific steps 61, 62, 6
3, 63' and the steps 7, 8 for general passengers have the same depth L, the distance between the pins 66a and 66b of the support link 66, the distance between the pin 66b of the support link 66 and the shaft 631a, and the support link 67. The distance between the pins 67a and 67b of the support link 67 and the distance between the pins 66a and 67a of the support link 67 are also L, and the front end A7 of the general passenger step 7 and the pin 67a, and the front end A61 of the specific step 61 and the pin 66a are parallelograms. The shape is such that the front end A8 pin 67b of the general passenger step 8, the front end A7 of the general passenger step 7, and the pin 67a are parallelograms, and the front end A63' and axis 631'a of the specific step 63' and the general passenger step 8 are shaped like a parallelogram. If the front end A8 and the pin 67b are constructed so as to always form a parallelogram, the steps 7 and 8 for general passengers each have a radius L about the pins 66a and 67a of the support link 67 with respect to the upper step.
Therefore, the riser 61a of the specific step 61 and the general passenger step 7
and 7a have a shape that draws a curved surface with a radius L around the front ends A61 and A7, respectively. However, for the specific step 63', the upper specific step 63'
Since the distance between the shaft 631a of the third step 631 and the shaft 631'a of the lower specific step 63' remains constant, the pin 67b of the general passenger step 8 ends up
and the axis 631'a of the specific step 63' is equal to the depth dimension L of the step in the horizontally movable portion of the escalator, and at a predetermined inclination angle, the axis 631'a moves into the elongated hole 67c of the support link 67 depending on the angle. In order to draw a trajectory that gradually becomes longer than L by sliding, the curved surface of the riser 8a of the step 8 for general passengers must be formed so as to draw a curved surface whose radius gradually changes around the front end A8.

In an escalator with such a configuration, only the specific steps 63 and 63' of the unit steps 300 are driven directly by the drive chain 22, but the specific steps 61 and 62 are driven via the support link 66, and the general passenger steps are driven by the support link 66. link 66
and 67, the unit step 30
The entire 0 will be driven. The support link 66 also functions to improve the rigidity of the large step 60, and the support link 67 also functions to maintain the horizontal state of the steps 7 and 8 for general passengers. At the inverted portion of each hinge 66c, 66d
67d, 67e, and 67f, the link itself does not become tensed and hinder movement of the escalator when driving the drive chain 22.

Such an escalator would have regular combinations of large steps that are wider in depth than steps for general passengers and steps for general passengers having a predetermined depth dimension (all three of the above-mentioned embodiments have three steps). An example of a large step configured with specific steps is shown, but this is for cases such as large wheelchairs that require a depth of approximately 1 meter, and cases where the number of specific steps is large, such as strollers, shopping cars, or children's wheelchairs. Because of the configuration in which the unit steps obtained by the above method (in some cases, two steps are sufficient) are connected in an endless manner, the maximum inclination of the escalator can be achieved by simply changing the number of consecutive steps for general passengers without changing the riser height of each step. It is possible to obtain an escalator whose angle can be arbitrarily selected and which can be used safely by a disabled person using a wheelchair and which requires the minimum necessary installation space.

In addition, in the case of such escalators, if even a wheelchair passenger learns the arrangement pattern of the unit steps, it is not necessary to stop the escalator when boarding (the regular steps can be modified to accommodate wheelchairs, etc.). In the case of escalators whose shape and size can be modified, the escalator must be stopped when a wheelchair passenger car is in use.) It is possible to transport passengers continuously.

[Problem to be solved by the invention]

However, for passengers who are not used to such escalators that can be used by general passengers and wheelchair passengers, especially wheelchair passengers, it is difficult to see when the large steps will come out from below the floor plate of the escalator entrance. Because you never know what will happen, it can be quite uneasy to get on an escalator that is running continuously due to the timing.If you hesitate at the entrance, it will disrupt the smooth flow of traffic, and the large steps will cause trouble. If a wheelchair passenger is unable to get on the vehicle properly, there is a risk of a fall and serious injury.

The present invention has been made in view of the above points, and is an escalator that can be used for both general passengers and wheelchair passengers, and which allows even inexperienced passengers to use the escalator with peace of mind by notifying passengers of the timing of boarding the large steps. The purpose is to provide

It is something.

〔Example〕

Hereinafter, one embodiment of the present invention will be described with reference to the drawings, taking the case of the tiltable escalator shown in FIG. 3 as an example.

Fig. 1 is a schematic diagram showing the overall configuration of a wheelchair-accessible escalator, and Fig. 8 shows, for example, the large step 1.

Yes, 2nd in the diagram
Components with the same reference numerals as those in FIG. 3 and FIG.
is the shaft of the drive device 210, 212 is the drive device 210
A drive chain that transmits power by being wound around a gear (not shown) fixed to a shaft 211 and a sprocket 214 fixed to a shaft 213;
215 is a step drive sprocket fixed to the shaft 213, and a large step 1 is connected between it and the driven side step sprocket 216 on the lower floor.
0 and a step chain 20 connected to general passenger steps 3 and 4 are wound around the step chain 20. And 217 is the floor plate of the lower floor, 21
7' is the floor plate of the upper floor, and these floor plates 217 and 217' have a parapet as shown in Fig. 9 (showing the floor plate part of the lower floor, and the floor plate of the upper floor is the same, so the illustration is omitted). A plurality of indicator lights 217a to 217f are provided along the balustrade 2 nearer to the 2 side, and similar indicator lights 217a to 217f are also provided on the inner surface of the balustrade 2. LS1 is a limit switch that operates when the large step 10 reaches below the floor plate 217. For example, as shown in FIG. This particular step 13 is connected to the floor plate 21 by the exit part.
7, the limit switch LS1 is operated. In LS2, the large step 10 is now the floor plate 217'
Although not shown, it is configured to operate when the extended shaft of the rear wheel 112 of the specific step 11 comes into contact with it, for example. Next, 220 in FIG. 10 is a notch 2 fixed to the shaft end of the shaft 211 of the drive device 210.
20a (this disk 220 may be provided on the shaft 213 of the step drive sprocket 215), and the PHS1 has a projector PHS1a and a light receiver PHS1b installed so as to face each other with the disk 220 in between. , notch 2 of disc 220
A photoelectric device configured such that the light beam from the light emitter PHS1a reaches the light receiver PHS1b only when 20a is in between, and outputs a high level signal when the light is received. PHS2 is a light emitter similar to the photoelectric device PHS1.
Only when the notch 220a of the disc 220 is located between the PHS2a and the receiver PHS2b, the light beam is transmitted to the receiver.
This is a photoelectric device that outputs a high level signal when light is received and is arranged so as to reach PHS2b.
20 notches 220a or more apart from each other by a circumferential distance. In other words, the arrangement is such that regardless of the rotational state of the disk 220, a state in which both the light receivers PHS1b and PHS2b are receiving the light beam always occurs. Therefore, the photoelectric devices PHS1 and PHS2
The outputs generate level signal outputs with different phases as shown in FIG. 12 depending on the rotating direction of the disc 220, that is, the operating direction (moving direction) of the escalator.

In FIG. 11, when a clock pulse is input to the clock input terminal C _A , FF _A , for example,
It is a positive edge trigger type D flip-flop that operates at the rising edge of the clock, and the input applied to the D _A input terminal appears as it is at the output terminal Q _A by applying a clock. FF _B is also a positive edge trigger type D flip-flop, and when a clock pulse is input to the clock input terminal C _B , the input applied to the D _B input terminal at the rising edge of that clock pulse is directly output to the output terminal Q _B. . In FIG. 11, a signal from the photoelectric device PHS1 is input to the D _A terminal and the C _B terminal, and a signal from the photoelectric device PHS2 is input to the C _A terminal and the D _B terminal. AND1 and AND2 are logical product elements, and the signal waveforms of the outputs Z _A and Z _B of the D flip-flops FF _A and FF _B and the logical product elements AND1 and AND2 are as shown in FIG. Therefore, when rotating clockwise (hereinafter considered as the case where the escalator is running in the UP direction), a pulse signal output is obtained only at the output Z _A of AND1, and when rotating counterclockwise (hereinafter considered as the escalator operating in the UP direction), but
(considering the case of operation in the DOWN direction), a pulse signal output is obtained only at the output Z _B of the AND element AND2. Here, it is possible to easily configure the circuit to generate pulse signal outputs based on the direction of the operation command, but with this circuit configuration, if the escalator step moves in a direction different from the direction of the operation command, It is possible to detect abnormalities immediately. Next, OR _A and OR _B are logical sum elements, AND3, AND4, AND5, AND6 are logical product elements, and FF _C sets a high level signal to the reset input terminal R _A when a high level signal is input to the S _A input terminal. High is applied to the output terminal _QC unless the signal is input.
Similarly, the well-known RS flip-flop FF _D , which continuously outputs a high-level signal, resets the reset input terminal R _B when a high-level signal is input to the S _B input terminal.
The RS flip-flop continues to output a high level signal to the output terminal _QD unless a high level signal is input to the RS flip-flop, and LS1a is the limit switch LS.
1 is a contact that closes when the limit switch LS2 is activated, LS2a is a contact that is closed when the limit switch LS2 is activated, +v is a positive power supply voltage, and R ₁ and R ₂ are resistors.

Now, when the escalator is running in the UP direction, the output _ZA of the logical product element AND1 is emitting a pulse signal as described above, and the RS flip-flop remains active until the limit switch LS1 operates.
Since the output terminal Q _c of FF _c is in the LOW level state, the gate of the AND element AND3 is closed, so no signal is transmitted to the destination. However, the escalator
While driving in the UP direction, the large step 10 circulates to the lower floor entrance and the limit switch is activated.
When LS1 operates, contact LS1a closes and a signal is applied to the output terminal Q _c of RS flip-flop FF _c .
A high level signal is output and that state is maintained. (In this case, the output Z _B of the AND element AND2 does not emit a pulse signal, so it is not immediately reset.) Therefore, the gate of the AND element AND3 opens and transmits the pulse signal first. CTA,
Both CTBs are 3-bit counters that count the pulses input to the pulse input terminals C ₁ and C ₂ respectively. That is, when the escalator is in UP operation, the counter CTA counts the pulses generated every time the large step 10 moves a predetermined distance after the limit switch LS1 operates, and outputs the corresponding binary output from the terminals Q _A0 ~ Q Output to _A2 . On the other hand, counter CTB indicates that the escalator
In the case of DOWN operation, the pulses generated every time the large step 10 moves a predetermined distance after the limit switch LS2 is activated are counted, and the corresponding binary output is outputted to the output terminals Q _B0 to Q _B2 . DCDA is the indicator light 217a to 2 shown in FIG.
17f is a display decoder for lighting up, for example, when the counter CTA counts one pulse and only the output terminal Q _A0 becomes a high level, it emits a high level output only to the output terminal a and lights up only the indicator light 217a. When the counter CTA counts 2 pulses and only the output terminal Q _A1 becomes a high level, a high level output is generated only to the output terminal b (for example, when the specific step 10 is cycled to the position shown in Fig. 9), it is displayed. Only light 217b is lit (indicator light 2
When the counter CTA counts 3 pulses and the output terminals Q _A0 and Q _A1 become high level, a high level output is generated only to the output terminal C, and only the indicator lamp 217c is turned on (the indicator lamp 217a is turned off).
7b goes out), and in the same manner, counter CTA counts 6 pulses and output terminals Q _A2 ,
When Q _A1 becomes High level, only the output terminal f
A high level output is generated to light only the indicator light 217f. Then, the counter counts 7 pulses and the output terminals Q _A0 , Q _A1 , and Q _A2 are all high.
When the level is reached, all the output terminals a to f are set to the LOW level, all indicator lights 217a to 217f are turned off, and a HIGH level signal is input to the clear input terminal CLR _A of the counter CTA via the AND element AND5. Clear the counter to its initial state, AND AND5 and ORA
A high level signal is input to the reset input terminal _RA of the RS flip-flop _FFC via the RS flip-flop FFC, and the RS flip-flop _FFC is also reset to the initial state.

In addition, the counter CTB and display decoder when the escalator is operated in the DOWN direction.
Since the DCDB is exactly the same, the explanation will be omitted, but in the case of escalator operation direction, that is, UP operation, the signal Z _A is sent to the DOWN RS flip-flop FF _D through the logical sum element ORB, and in the case of DOWN operation, the signal Z A is sent through the ethical sum element ORA. Since the signal Z _B is periodically input to the UP RS flip-flop FF _C as a reset signal, when the driving direction is switched,
The RS flip-flops FF _C and F _D are configured so that they can always start from the initial state.

In the above explanation, the indicator lights 217a to 217f repeatedly turn on and off every time the counter CTA counts one pulse. Indicator lights 217a to 217
It is possible to configure the circuit so that f repeatedly turns on and off, or it is easy to configure the circuit so that it turns on one after the other (without turning off the indicator light that was lit first), so this is an example. but not limited to. In short, we provide guidance to passengers so that they can clearly see when large steps will appear based on the illumination of the indicator lights installed near the entrance (which can be installed on the floor plate or handrail alone, or on the skirt panel). As long as it is possible, the timing of the boarding operation may be guided not only by the indicator light but also by sound or voice.

However, in the case of the indicator lights disclosed in the embodiment, the disc 220 shown in FIG. Notch 2 to be provided
It is desirable to optimally set the number of counters 20a or to appropriately determine the count numbers of the counters CTA and CTB.

Furthermore, it is clear that the present invention can be used not only for the above-mentioned tiltable escalator but also for conventional escalators for wheelchair passengers and the like. Furthermore, it would be even more effective in terms of safety if a similar guide device is provided near the exit of the escalator to guide passengers when they get off the escalator.

〔Effect of the invention〕

As described above, according to the present invention, information regarding the movement of a large step that suddenly appears from a hidden position below the floor plate is displayed to the passengers in a timely and appropriate manner according to the actual moving direction of the escalator. Even inexperienced passengers such as people with disabilities can use escalators extremely safely. Furthermore, it is extremely easy to check whether the actual movement of the escalator is normal in response to the driving direction command, and the present invention can also be applied to automatic escalators where the driving direction of the escalator changes constantly depending on the situation. It is possible.
