Description

  The present invention relates to passenger conveyors such as escalators and electric roads, and more particularly to passenger conveyors that detect operation of passengers and control operation.

  Conventionally, a passenger conveyor that detects a passenger's state, for example, a moving speed and controls operation, has already been proposed in Patent Document 1, for example.

JP 2002-104761 A

  The passenger conveyor described in Patent Literature 1 detects at least two detectors at intervals in order to detect the moving speed (state) of the passenger, and detects the time for the passenger to pass between them. And the distance between the two detectors, the movement speed of the passenger is obtained, and the movement speed of the tread is changed (controls the operation) based on the passenger movement speed.

  However, it has not been considered to safely control the operation of the passenger conveyor by detecting a fall or collection as the passenger state.

  An object of the present invention is to provide a passenger conveyor capable of detecting a passenger's moving speed, as well as detecting a passenger's falling or gathering and operating safely.

  In order to achieve the above object, the present invention provides first passenger detection means and second passenger detection means for detecting a moving speed of a passenger moving on the getting-on / off floor on both sides in the width direction, and the first passenger detection The third passenger detection means for detecting the passage of passengers on the side closer to the tread board than the means and the second passenger detection means is provided, and the first to third passenger detection means are configured so that the passenger can be detected independently, A control device for controlling the operation based on the time detected by the first to third passenger detection means and the reference time is provided.

  In general, the time required for a passenger to step on the landing foot to be lifted off the landing is naturally slower for elderly people and physically disabled persons than for healthy persons, and is faster for young healthy persons. Therefore, when the movement time from the stepping of the passenger's foot to the kicking is detected by the first and second passenger detection means and compared with the reference movement time, the movement speed of the tread is slowed down and fast. In this case, the current tread board moving speed is maintained or increased within an allowable range.

  Furthermore, when a passenger falls on the boarding / exiting floor and cannot get up, the travel time detected by the first and second passenger detection means and the third passenger detection means is not suitable for elderly people or inconveniences to the body. Therefore, it is possible to rescue a fallen person by performing control such as stopping the operation of the passenger conveyor.

  Further, when the vicinity of the boarding / exiting floor on the exit side is crowded due to congestion, the first and second passenger detection means detect the passage of passengers while the third passenger detection means detects the passage of passengers. The traveling time is longer than the traveling time of elderly people and physically disabled people, so it is possible to know that the vicinity of the boarding / exiting floor is congested. In such a case, by slowing down the moving speed of the passenger conveyor, the passenger who got down on the boarding floor first can leave the boarding board earlier than the next passenger who gets off the boarding floor. Can be prevented.

  ADVANTAGE OF THE INVENTION According to this invention, the passenger conveyor which can drive | operate safely by detecting a passenger's fall and collection as well as the detection of the moving speed of a passenger can be obtained.

  A first embodiment of a passenger conveyor according to the present invention will be described below with respect to an escalator shown in FIGS.

  In general, the escalator 1 includes a frame 4 supported across the upper floor 2 and the lower floor 3, a step 5 having a step plate on the upper surface, and left and right balustrades 6 erected on both sides in the moving direction of the step 5. And a handrail 7 that moves while being guided by the periphery of the balustrade 6 and boarding / exiting floors 8A and 8B for getting on and off the step 5.

  A plurality of the steps 5 are connected to the step chain 9 in an endless manner, and are circulated and guided by guide rails (not shown) provided on the frame body 4. The step chain 9 is wound around a drive sprocket 10 supported on one side in the longitudinal direction of the frame body 4 and a driven sprocket 11 supported on the other side in the longitudinal direction of the frame body 4. It has been. The drive sprocket 10 is driven by a drive device 12 installed in the vicinity, and the moving handrail 7 is also driven in synchronization with the step 5 by the power of the drive device 12.

  The balustrade 6 includes a balustrade panel 13 erected along the moving direction of the step 5, a skirt guard 14 that partitions the balustrade panel 13 and the step 5, and an inner deck cover 15 that covers the skirt guard 14. The outer deck cover 16 that covers the outer side of the base of the balustrade panel 13, and the end portion that covers the terminal portions of the skirt guard 14, the inner deck cover 15, and the outer deck cover 16, and is formed with an entrance through which the moving handrail 7 enters and exits. It is comprised by the balustrade member which consists of the cover 17. FIG.

  The first light reflecting sensor 18A and the second light reflecting sensor 18B, which serve as first passenger selecting means and second passenger detecting means, get on and off the left and right end cover 17 that are the balustrade members of the escalator 1 configured as described above. It is attached at a height of 15 to 20 cm from the floor 8A (8B) surface. Each of the first and second light reflection sensors 18A and 18B is configured to emit a detection beam and capture the reflected light to emit a detection signal. And these 1st and 2nd light reflection type sensors 18A and 18B are installed so that a detection beam may be radiated | emitted so that it may become substantially parallel with the floor surface of the boarding / alighting floor 8A (8B), and pass the passenger M1 which passes. In order to be able to detect all, it is installed so that a detection beam may be radiated in a direction intersecting the passenger traveling direction. Specifically, the detection beam intersects at the center in the width direction of the getting-on / off floor 8A (8B) before reaching the direction changing portion 7E of the moving handrail 7, and the detection beam extends from the intersection to about 30 cm ahead. And the 2nd light reflection type sensors 18A and 18B are installed. And these 1st and 2nd light reflection type sensors 18A and 18B are comprised by the independent circuit, and each detect the operation | movement of a passenger independently.

  Further, a third light reflection method which is a third passenger detection means for detecting the passage of a passenger to the skirt guard 14 which is a balustrade member closer to the step 5 than the first and second light reflection sensors 18A and 18B. A sensor 19 is provided. The third light reflection sensor 19 is the same type as the first and second light reflection sensors 18A and 18B, and is parallel to the width direction of the passenger floor 8A (8B) and orthogonal to the passenger traveling direction. In addition, it is configured to radiate a detection beam, and is composed of a circuit independent of the circuits of the first and second light reflection sensors 18A and 18B, and detects the movement of a passenger alone. is there.

  The detection signals from the first to third light reflection sensors 18A, 18B, and 19 are respectively input to the control device 20 installed in the vicinity of the driving device 12, and are calculated in the control device 20. As a result of calculation in the control device 20, priority is given to the detection signal with a longer passenger movement time (detection time is longer), and the drive device 12 is instructed based on this detection signal to stop the movement speed of the step 5, Change to high speed or low speed.

  As described above, the first and second light reflection sensors 18A and 18B are provided on the end cover 17, and the third light reflection sensor 19 is provided on the skirt guard 14, so that the passenger M1 is now in contact with the escalator 1. When trying to get in from the center in the width direction, the foot of the passenger M1 blocks the detection beam from the light reflecting sensors 18A and 18B, and the reflected light returns to the light reflecting sensors 18A and 18B, so that a detection signal is output. .

  FIG. 4 shows an example of detection signals from the first and second light reflecting sensors 18A and 18B during boarding. In FIG. 1, the position where the right foot of the passenger M1 crosses the detection beam about 30 cm away from the beam intersection of the detection beam from the second light reflection type sensor 18B is b1, and the left foot of the passenger M1 is from the second light reflection type sensor 18B. The position crossing the detection beam before the beam intersection of the detection beam is point b2, and the position where the left foot of the passenger M1 crosses the detection beam about 30 cm from the beam intersection of the detection beam from the first light-reflective sensor 18A. A1 point, the position where the right foot of the passenger M1 crosses the detection beam before the beam intersection of the detection beam from the first light reflection type sensor 18A is the point a2, and the upper side in FIG. 4 is due to the light reflection type sensor 18B The detection signal was displayed as the detection signal by the light reflection type sensor 18A on the lower side.

  In FIG. 4, the reference movement time is set such that the movement time Tb1 detected by the first light reflection type sensor 18A and the movement time Tb2 detected by the second light reflection type sensor 18B are the same. If it is substantially the same as Tb2, it is determined that the person is a normal healthy person, and the control device 20 instructs the drive device 12 to drive the step 5 at the standard speed. Compared with the movement times Tb1 and Tb2, if the movement times To1 and To2 are longer than the movement times Tb1 and Tb2, it is determined that the elderly person or the physically handicapped walking weak person, and the control device 20 sends a step 5 to the driving device 12. To operate at low speed. On the other hand, if the movement times Ty1 and Ty2 are shorter than the movement times Tb1 and Tb2 compared to the movement times Tb1 and Tb2, it is determined that the person is a young person, and the control device 20 causes the driving device 12 to move the step 5 at the standard speed. Command to drive or drive at a higher speed allowed than the standard speed.

  If a difference occurs in the detection time by the first and second light reflection sensors 18A and 18B, for example, To1> To2, the control device 20 gives priority to the detection signal having the longer detection time, and the driving device 12 It is advantageous for weak walkers.

  On the other hand, the third light reflection type sensor 19 detects the passage of the passenger by crossing immediately before the passenger detected by the first and second light reflection type sensors 18A and 18B gets on the step 5, and controls the detection signal. Output to the device 20. Using the detection signal from the third light reflection type sensor 19 as a trigger, the operation of the escalator 1 is started at the commanded moving speed and operating time of the step 5. It should be noted that if a passenger is detected by the first and second light-reflective sensors 18A and 18B and the third light-reflective sensor 19 does not detect the passenger even after a predetermined time has passed, a predetermined time is required. Later, the escalator 1 is switched to a slow speed operation or stopped, and a standby operation is performed. If a passenger is detected by the third light reflection type sensor 19 during the standby operation, the operation is switched to the slow speed operation or the low speed operation.

  From the above, even in the escalator that performs the automatic operation of driving the step 5 at the reference speed when the passenger is detected by stopping the movement of the step 5 at a slow speed or a low speed when it is quiet, and detecting the passenger, the type of the passenger is accurately determined. It is possible to start operation at a different operation speed. Needless to say, even in an escalator in which the step 5 is always operated at a reference speed even when it is quiet, it is possible to determine the type of passenger and change the speed to an appropriate driving speed.

  By the way, the passengers who are physically handicapped are inevitably slow, and when they get on, they are stepped on the step 5 and fall to the rear, and when getting off, they hit the comb teeth at the tip of the boarding floor 8A (8B). There is a risk of tipping forward. Should such a fall accident occur, the escalator 1 must be immediately stopped to rescue the faller.

  An example in which a fallen person at the time of boarding is detected by the first to third light reflection sensors 18A, 18B, 19 will be described with reference to FIGS.

  For example, when a passenger M1 who is handicapped falls on his / her back as shown in FIG. 5 when he / she gets on his / her foot at the moment he / she tries to put his / her weight on the step 5, the first to third light reflection type The detection signals of the sensors 18A, 18B, and 19 are as shown in FIG. That is, in FIG. 6, the passenger M1 is detected at the points a1, a2, b1, and b2 by the first and second light reflecting sensors 18A and 18B before the fall, and the passenger's feet are detected by the third light reflecting sensor 19 in FIG. Crossing is detected (c). Thereafter, when the passenger M1 falls over as shown in FIG. 5 in order to put his weight on the step 5, the third light reflecting sensor 19 first detects that both feet have crossed simultaneously in the direction opposite to the boarding direction (d). Thereafter, the body is detected across the first and second light-reflective sensors 18A and 18B (e, f). And when the signal which detected the fallen body is output continuously longer than the movement time of an elderly person or a physically handicapped person, it judges that the fallen passenger M1 has received the big damage. Then, the control device 20 stops the operation of the escalator 1. At the same time, the manager room is notified of the occurrence of an abnormal situation. When the fallen passenger M1 stands up by himself without being damaged, the output of the detection signals e and f in FIG. 6 becomes zero, and the operation of the escalator is continued.

  Even if the foot of the fallen passenger M1 hits the position of the third light reflection type sensor 19, if the height of the faller's foot is less than 15 cm from the landing floor 8A (8B), the same signal as in FIG. Is output. However, if the height of the faller's foot is 15 cm or more from the getting-on / off floor 8A (8B), the signal d in FIG. 6 is continuously output as shown by a two-dot chain line.

  Next, detection of a fallen person when getting off will be described. In a fall accident when getting off, the passenger's foot hits the comb teeth at the tip of the boarding / alighting floor 8A (8B) and falls to the front side (passenger M1 becomes prone in FIG. 5). When the vehicle falls to the front side, first, it crosses the first light reflection type sensor 18A and 18B after crossing the third light reflection type sensor 19, so that the detection signal thereof is from d to e and f in FIG. It becomes a waveform and can be detected in the same way as a fall at boarding. That is, if a signal that detects a fallen body is output continuously for longer than the movement time of an elderly person or a physically handicapped person, it is determined that the fallen passenger M1 has received significant damage. Then, the control device 20 stops the operation of the escalator 1. At the same time, the manager room is notified of the occurrence of an abnormal situation. When the fallen passenger M1 stands up by himself without taking damage, the output of the detection signals e and f in FIG. 6 becomes zero, and the operation of the escalator is continued.

  On the other hand, when the area around the getting-on / off floor on the exit side is crowded as shown in FIG. 7, the detection waveforms of the first to third light reflection sensors 18A, 18B, and 19 are as shown in FIG. As shown. That is, since the passenger first traverses the third light reflection type sensor 19 with his / her foot, the detected waveform 19W becomes a discontinuous fine waveform, and this state continues until congestion is reduced. Next, a large number of passengers cross the first and second light reflection type sensors 18A and 18B. At this time, the detection beams are emitted obliquely in the direction of movement of the passengers. The detection waveforms 18AW and 18BW by the reflected detection beam are continuously output.

  Therefore, the discontinuation of the escalator by the discontinuous detection waveform 19W output from the third light reflection type sensor 19 and the continuous detection waveforms 18AW and 18BW output from the first and second light reflection type sensors 18A and 18B. It is possible to grasp that the mouth side is congested and in a dangerous state, and the control device 20 changes the moving speed of the step 5 to a low speed. As a result, the passenger who first gets on the boarding floor gets down next. It is possible to move away from the getting-on / off floor earlier than the incoming passenger, and it is possible to prevent accidents such as shogi defeat due to collection.

  Note that the detected waveforms 18AW and 18BW are not always output continuously even when the passengers are congested. Of course, if there is a passenger interval, the waveforms may be momentarily interrupted. However, even if such momentary waveform breaks are continuously output, this is due to the result of crowded passengers, so naturally the control of the moving speed of the step 5 to prevent accidents due to gathering. It is necessary to do.

  As described above, according to the present embodiment, not only the moving speed of the passenger can be detected, but also the falling or collecting of the passenger can be detected and the driving can be performed safely.

  In the above embodiment, the first and second light reflection sensors 18A and 18B are provided on the lower end cover 17, so that the first and second light reflection sensors 18A and 18B As a result, the movement speed of the passenger can be accurately detected without being influenced by the shaking of the passenger's hand.

  Further, when the length dimension of the baggage in the traveling direction is larger than the dimension between the passenger's dorsal belly, the detection time becomes longer when the baggage is detected by the light reflection type sensors 18A and 18B. In some cases, it is determined that the person is an elderly person or a physically handicapped person, and the moving speed of the step 5 is switched from the standard speed to the low speed driving. Therefore, it becomes a low-speed driving that is meaningless for healthy people and young people. In order to eliminate such inconvenience, in the present embodiment, the installation positions of the first and second light reflecting sensors 18A and 18B, particularly the installation height, are set to the positions where the passenger's feet are radiated. More specifically, when passengers with baggage and passengers without baggage are detected in the same way, it is necessary to correctly determine whether the person is an elderly person, a physically handicapped person, or another person. It is desirable to install the first and second light reflecting sensors 18A and 18B within a range of 5 cm to 20 cm above the floor surface of (8B). That is, when a healthy person walks, the height of the heel when stepping on the foot is about 3 cm from the ground, and the first and second light reflecting sensors 18A, 18B are set to a height of less than 5 cm. If installed, the foot on the passenger's stepping side may not be detected. Therefore, the installation height of the first and second light reflection sensors 18A and 18B is set to 5 cm or more. Further, when the first and second light reflecting sensors 18A and 18B are installed at a height of 20 cm or more from the floor surface, the length dimension in the traveling direction of the baggage is larger than the dimension between the passenger's back and abdomen. The passenger movement speed may not be detected. For this reason, it is desirable to install the first and second light reflection sensors 18A and 18B within a range of 5 cm to 20 cm above the floor surface of the passenger floor 8A (8B). Considering that the reflective sensors 18A and 18B are provided on the end cover 17 that is a balustrade member of the escalator 1, it is most effective to install the sensors at a position 15 cm above the floor surface of the passenger floor 8A (8B).

  Thus, by installing the first and second light reflecting sensors 18A, 18B at a position 15 cm above the floor of the passenger floor 8A (8B), the length dimension in the traveling direction is temporarily between the passenger's back and abdomen. Even when a baggage larger than the above size is detected, the length dimension in the direction of travel of the baggage at 15 cm above the floor is substantially within the stride of the passenger, so it is almost the same as detecting the stride of the passenger. .

  Therefore, even if the passenger has a baggage larger than the size between the passenger's backs, the moving speed can be detected with high accuracy. The detection signal has a detection signal pattern substantially the same as that in FIG.

  That is, a passenger with baggage is measured by the first and second light reflection sensors 18A and 18B, and if the detection signal ON time is substantially the same as the reference movement time Tb1, it is determined that the passenger is a normal healthy person. The control device 20 instructs the drive device 12 to drive the step 5 at the standard speed. Compared with the reference movement time Tb1, if the movement time To1 is longer than the reference movement time Tb1, it is determined that the person is an elderly person or a physically handicapped person, and the moving speed of the step 5 from the control device 20 to the driving device 12 is determined. To operate at low speed. On the contrary, if the movement time Ty1 is shorter than the reference movement time Tb1 compared to the reference movement time Tb1, it is determined that the person is a young person, and the control device 20 sets the step 5 to the standard speed or the standard speed with respect to the drive device 12. Command to drive at a higher speed allowed. Such a detection signal pattern is a detection signal pattern obtained even when a long skirt is worn without carrying baggage.

  On the other hand, the first and second light-reflective sensors 18A are used for passengers having no baggage or having a baggage whose length in the traveling direction is smaller than the dimension between the backs of the passengers, and passengers who do not wear a long skirt. , 18B, two types of detection signal patterns are obtained for one passenger. The first type of detection signal pattern is a case where the foot that the passenger steps on is positioned on the detection beams of the first and second light reflection type sensors 18A and 18B. The detection signal pattern at that time is the same as the detection signal pattern in FIG. 4 because a signal until the stepped-on foot is kicked up is output. The second type of detection signal pattern is a case where, for example, the passenger's right foot (left foot) crosses the detection beam of the first and second light reflecting sensors 18A and 18B. The detection signal pattern at that time is the detection signal of the right foot (left foot) that has previously crossed the detection beams of the first and second light reflection sensors 18A and 18B, and then the first and second light reflection sensors 18A, It becomes a detection signal pattern of two peaks with the detection signal of the left foot (right foot) crossing the detection beam of 18B. By comparing the time Tb1 (To1, Ty1) between the two mountains with the reference movement time Tb1, it is possible to determine whether the person is a healthy person, an elderly person, or a young person, and the moving speed of the step 5 can be changed or maintained. .

  By the way, it takes about 1 second to completely switch the moving speed of the step 5 after detecting the passenger. Therefore, if a standard passenger travels 1 meter per second, the passenger is detected by the first and second light reflection sensors 18A and 18B so that the passenger reaches the step 5 after 1 second. Can be placed on the step 5 after the speed change. For this purpose, it is desirable to install the first and second light reflecting sensors 18A and 18B, which are passenger detection units, at a position about 1 m away from the step-side tip of the getting-on / off floor 8A (8B) to the opposite step side. Therefore, since the average dimension from the step side tip of the boarding / alighting floor 8A (8B) to the direction changing portion 7E of the moving handrail 7 is 0.8 m, the first and second light reflecting sensors 18A and 18B are connected to the moving handrail 7 It is installed so as to emit a detection beam so that the passenger M1 can be detected on the getting-on / off floor 8A (8B) on the opposite side of the step from the direction changing portion 7E. However, since the speed change of the step 5 is changed slowly, even if it is a healthy person, even if it gets in the step 5 in the middle of the speed change, it will not be taken, and may be detected within 1 m. . Moreover, since the walking speed is slow for the elderly and the physically handicapped, for example, even if it is detected by the direction changing portion 7E of the moving handrail 7 that is about 0.8 m away from the step side tip of the getting-on / off floor 8A (8B), it is sufficient. The moving speed of the step 5 can be changed.

  In addition, by providing the first and second light-reflective sensors 18A and 18B on the left and right balustrade members, as shown in FIG. 1, it is possible to detect all passengers M1, M2, and M3 trying to get in from any position. The detection area can be completely placed on the boarding / alighting floor 8A (8B) on the side opposite to the step with respect to the direction changing portion 7E of the moving handrail 7. As a result, since the distance from the passenger detection position to the step 5 can be ensured, it is possible to avoid the passengers M1 to M3 getting on the step 5 whose moving speed is being changed.

  Further, the above explanation is an example of detecting the moving speed of one passenger M1 (M2 or M3) who tried to get into the escalator 1, but as shown by the two-dot chain line in FIG. When M3 gets in side by side, each passenger M2, M3 is set so that the first and second light reflecting sensors 18A, 18B can be detected independently, so that two passengers M2, M3 When boarding in a line, the moving speed of each passenger M2, M3 can be detected independently. And when two passengers M2 and M3 get on side by side, a weak walking person may line up with a healthy person and a youth. In such a case, since the moving speed of the step 5 is supported by giving priority to the detection signal having a long moving time, the moving speed of the step 5 can be changed according to the weak walking person.

  By the way, in the present embodiment, the detection beams of the first and second light reflecting sensors 18A and 18B intersect at the center in the width direction before reaching the direction changing portion 7E of the moving handrail 7, and further, about 30 cm from this intersection. It is intended to extend to the past. The reason is that each detection beam always detects the left and right feet of the passenger. Specifically, referring to FIG. 1, the first light reflection sensor 18A detects the left and right feet of the passenger M2 with the detection beam, and the second light reflection sensor 18B detects the left and right feet of the passenger M3 with the detection beam. . For the passenger M1 who wants to get in from the center, the first and second light reflection sensors 18A and 18B respectively detect the left and right feet of the passenger M1 with each detection beam. However, if the radiation distances of the detection beams of the first and second light reflection sensors 18A and 18B are up to the beam intersection, the first and second light reflection types are applied to the passenger M1 who tries to get in from the center. Only one foot can be detected by the sensors 18A and 18B, respectively, and the moving speed of the passenger cannot be detected. Therefore, the detection beams of the first and second light reflecting sensors 18A and 18B need to intersect once and extend about 30 cm away from the intersection.

  9 and 10 show a second embodiment of a passenger conveyor according to the present invention. The same reference numerals as those in FIGS. 1 to 3 denote the same components, and thus detailed description thereof is omitted.

  In the first embodiment, the end cover 17 of the escalator 1 is provided with the first and second light reflection sensors 18A and 18B. As shown in FIGS. When the guide fences 21A and 21B are installed on both sides of 8A and 8B, the first and second light reflecting sensors 18A and 18B may be installed using the guide fences 21A and 21B. In this case, it goes without saying that the passenger detection area is the same as that in the above embodiment.

  In addition, when a wall exists on both sides of the escalator 1 instead of the guide fences 21A and 21B, the first and second light reflection sensors 18A and 18B can be installed using the walls.

  Further, as a modification of the second embodiment, first and second light reflection sensors are installed on the getting-on / off floors 8A (8B) near the end covers 17 on both the left and right sides to detect passengers. It may be. However, in this case, if the detection beam of the light reflection type sensor is radiated parallel to the floor surface, the passenger's feet may not be detected, so the range from 5 cm to 20 cm above the floor surface of the passenger floor 8A (8B). It is desirable to radiate the detection beam by tilting it upward so that the detection beam can be radiated.

  By the way, in the embodiment described above, the detection beams of the first and second light reflecting sensors 18A and 18B on both the left and right sides intersect with each other at the center in the width direction before reaching the direction changing portion 7E of the moving handrail 7 and further. It is installed to extend. However, in a specific area or building, half of the step 5 of the passenger conveyor in the width direction is secured as a walking path, and the remaining half of the step 5 in the width direction is divided as a passenger boarding portion. In the passenger conveyor which performs such use, the width direction of the passenger boarding part before the detection beams of the first and second light reflecting sensors 18A and 18B on the left and right sides reach the direction changing part 7E of the moving handrail 7 You may install so that it may cross in the center. In this way, by shifting the intersecting portion of the detection beams to the position side in the width direction, it is possible to accurately detect the moving speed of the passenger using half of the step 5 in the width direction as a walking path.

  In each of the above-described embodiments, the light reflection type sensor has been described as the passenger movement time detection unit.

  Furthermore, in each said embodiment, although the escalator was demonstrated as a passenger conveyor apparatus, it cannot be overemphasized, and it cannot be overemphasized that it can apply also to the electric road which does not produce a level | step difference between adjacent treads.
