By the way, in recent years, an accident that occurs when a user walks or runs on the steps of an escalator has been regarded as a problem. For example, while moving on a step, a user may come into contact with another user and cause him / her to fall or be injured. For this reason, users are being asked to refrain from moving on the steps by voice or display. However, with voice and display calls, users quickly become accustomed to the calls and have not been able to exert sufficient deterrence.

In consideration of these points, the illustrated escalator 1 is devised to suppress the movement of the user on the step 2. Specifically, the escalator 1 includes a lighting device 40 that illuminates the riser portion 22 with an image 60 (see FIG. 2) that gives the illusion of the height position of the tread surface 21a. By illuminating the riser portion 22 with the image 60 that gives the illusion of the height position of the tread 21a, it becomes difficult for the user to grasp the actual height position of the tread 21a, and it becomes difficult to climb the tread 2. As a result, the movement of the user on the step 2 can be effectively suppressed. Further, in general, it takes a relatively long time for the user to become accustomed to such an image 60 and to be able to accurately grasp the height position of the tread surface 21a. Therefore, the deterrent to the movement of the user can be effectively sustained.

First, the configuration of the lighting device 40 will be described in detail with reference to FIG. The lighting device 40 of the present embodiment includes first to third light irradiation units 41,42,43 that illuminate the riser unit 22, and a control device 44 that controls the light irradiation units 41,42,43. The lighting device 40 further includes a storage unit 45 for storing image information regarding the image 60 to be illuminated on the riser unit 22, and a receiving unit 46 for receiving control information. The receiving unit 46 receives the control information transmitted from the communication device 50 owned by the administrator of the escalator 1.

As can be understood from FIG. 1, the light irradiation units 41, 42, 43 are arranged in the space surrounded by the skirt guard 7. As can be seen from FIGS. 1 and 2, the first to third light irradiation units 41, 42, and 43 illuminate the riser unit 22 through the openings 7a, 7b, and 7c provided in the skirt guard 7, respectively. As a result, the lighting device 40 can effectively illuminate the step 2. The light irradiation units 41, 42, 43 may be provided on a column (not shown) that supports the column 6 or the column 6.

The control device 44 reads out image information corresponding to the control information input to the control device 44 via the receiving unit 46 from the storage unit 45, so that the image 60 corresponding to the image information is illuminated by the riser unit 22. Controls the light irradiation units 41, 42, 43. Further, the control device 44 controls the light irradiation units 41, 42, 43 so that the image 60 on the riser unit 22 is arranged at a position corresponding to the control information. Specifically, the control device 44 receives the light irradiation units 41, 42, so that the position where the image 60 is illuminated is the entire riser unit 22, the right half or the left half, according to the control information. Control 43. Further, the control device 44 controls the light irradiation units 41, 42, 43 so that the riser unit 22 is illuminated with the saturation and / or the brightness according to the control information. Further, the control device 44 controls the light irradiation units 41, 42, 43 so that the image 60 on the riser unit 22 follows the movement of the step 2 (of the riser unit 22). Specifically, the control device 44 controls the light irradiation units 41, 42, 43 based on the information regarding the rotation speed of the motor 31 input from the sensor 33.

Next, the image 60 illuminated by the lighting device 40 will be described with reference to FIGS. 2 and 4. Here, in FIGS. 2 and 4, and in FIGS. 5, 7, and 8, which will be referred to later, of the tread 2a of the tread 2 or the front edge 21b of the tread 21a, the tread 2a or the tread 2a illuminated by the lighting device 40 The front edge 21b is indicated by a broken line.

As described above, the lighting device 40 illuminates the riser portion 22 with an image 60 that gives the illusion of the height position of the tread surface 2a of the treads 2 arranged in a staircase pattern. In the illustrated example, the image 60 shows a plurality of line segments 61,62 parallel to each other extending in the vertical direction (the height direction of the step 2), and a part of the line segments 61 among the plurality of line segments 61, 62. It includes an inward arrowhead 63 attached to both ends and an outward arrowhead 64 attached to both ends of some of the other line segments 62 among the plurality of line segments 61 and 62. The image 60 including such a figure (or pattern) causes the observer of the image 60 to have an illusion of the length of the line segments 61 and 62, and accordingly the height position of the tread surface 21a.

Further, in the example shown in FIG. 2, the image 60 illuminated by the lighting device 40 is different for each step 2. As a result, it will take more time for the user to become accustomed to the image 60 and to be able to accurately grasp the height position of the tread surface 21a. As a result, the deterrent to the movement of the user can be maintained more effectively.

Further, in the illustrated example, the image 60 illuminated by the lighting device 40 is a moving image. For example, the image 60 shown in FIG. 4 changes to the image 60 shown in FIG. 5 after a predetermined time length has elapsed. Specifically, the position of the line segment 61 with the inward arrow feather 63 and the position of the line segment 62 with the outward arrow feather 64 in the image 60 change with time. As a result, it will take more time for the user to become accustomed to the image 60 and to be able to accurately grasp the height position of the tread surface 21a. As a result, the deterrent to the movement of the user can be maintained more effectively.

As shown in FIG. 2, the image 60 illuminated by the lighting device 40 may include a figure (or pattern) other than the figure (or pattern) that gives the illusion of the height position of the tread surface 21a. In the example shown in FIG. 2, the image 60 irradiated by the third light irradiation unit 43 includes a graphic 65 that urges the user to stop on the step 2. When the escalator 1 is an ascending escalator, if such a figure 65 is displayed on the riser portion 22 to which the user's line of sight is easily directed, the movement of the user can be suppressed. Of course, the place where the figure 65 is displayed is not limited to the riser unit 22. The figure 65 may be illuminated by, for example, the tread plate portion 21.

In the first embodiment described above, the lighting device 40 illuminates the riser portion 22 with an image that gives the illusion of the height position of the tread surface 21a, but the present invention is not limited to this. The lighting device 40 may illuminate the tread portion 21 with the image 60. Alternatively, the lighting device 40 may illuminate the image 60 on the riser portion 22 and the tread portion 21.

Next, a second embodiment of the escalator will be described with reference to FIGS. 6 and 7.

In the second embodiment shown in FIG. 6, the escalator 100 is a descending escalator, and the light irradiation units 41, 42, 43 of the lighting device 40 are arranged in the truss 5 instead of the skirt guard 7. However, the other configurations are substantially the same as those of the first embodiment shown in FIGS. 1 to 5. In the second embodiment shown in FIGS. 6 and 7, the same parts as those in the first embodiment shown in FIGS. 1 to 5 are designated by the same reference numerals, and detailed description thereof will be omitted.

In the example shown in FIGS. 6 and 7, the escalator 100 is a descending escalator spanned between the two floors F1 and F2 of the building. The entrance 110 of the escalator 100 is provided on the floor F2. The exit 111 of the escalator 100 is provided on the floor F1.

Each step 2 has a tread portion 21 including a tread surface 21a on which a user is placed, and a riser portion 22 connected to the front end of the tread portion 21 in the traveling direction of the step 2. The riser portion 22 covers the step between the step plate portion 21 of the step 2 and the step plate portion 21 of the other step 2 when the step 2 having the riser portion 22 is arranged in a staircase pattern together with the other step 2. As shown, it is connected to the tread plate portion 21.

As shown in FIG. 6, the light irradiating portions 41, 42, 43 of the lighting device 40 are arranged below the step 2 arranged in a staircase pattern, and illuminate the tread plate portion 21 from below the step 2. Then, the user can observe the image formed by the transmitted light transmitted through the tread plate portion 21.

The image 160 illuminated by the lighting device 40 is an image that gives an illusion of the position of the front edge portion 21b of the tread surface 21a in the traveling direction of the treadle 2. In the example shown in FIG. 7, the image 160 is attached to both ends of a plurality of parallel line segments 61,62 extending in the front-rear direction of the tread surface 21a and some of the plurality of line segments 61,62. It includes an inwardly-facing arrowhead 63 and an outward-facing arrowhead 64 attached to both ends of some of the other line segments 62 among the plurality of line segments 61 and 62. The image 160 including such a figure causes the observer of the image 160 to have an illusion of the length of the line segments 61, 62, and accordingly the position of the front edge portion 21b of the tread surface 21a. As a result, it becomes difficult for the user to grasp the position of the front edge portion 21b of the tread surface 21a, and it becomes difficult for the user to go down the tread step 2. Then, the movement of the user on the step 2 can be effectively suppressed. Further, in general, it takes a relatively long time for the user to become accustomed to such an image 160 and to be able to accurately grasp the position of the front edge portion 21b of the tread surface 21a. Therefore, the deterrent to the movement of the user can be effectively sustained.

Further, in the example shown in FIG. 7, the image 160 illuminated by the lighting device 40 is different for each step 2. As a result, it will take more time for the user to become accustomed to the image 60 and to be able to accurately grasp the position of the front edge portion 21b. As a result, the deterrent to the movement of the user can be maintained more effectively.

In the example shown in FIG. 7, the image 160 illuminated by the lighting device 40 is a still image that is stationary with respect to the step 2, but is not limited to this. Similar to the examples shown in FIGS. 4 and 5, the image 160 illuminated by the lighting device 40 may be a moving image.

Further, the image 160 illuminated by the lighting device 40 may include a figure (or pattern) other than the figure (or pattern) that gives an illusion of the position of the front edge portion 21b of the tread surface 21a, as in the example shown in FIG. For example, image 160 may include graphic 65 as shown in FIG. When the escalator 100 is a descending escalator, if such a figure 65 is displayed on the tread plate portion 21 to which the user's line of sight is easily directed, the movement of the user can be suppressed. Of course, the place where the figure 65 is displayed is not limited to the tread plate 21. The figure 65 may be illuminated, for example, on the boarding / alighting plate 9 of the exit 111.

In the second embodiment described above, the lighting device 40 illuminates the tread plate portion 21 with an image 160 that gives an illusion of the position of the front edge portion 21b of the tread surface 21a, but is not limited to this. The lighting device 40 may illuminate the riser unit 22 with the image 160. Alternatively, the lighting device 40 may illuminate the tread plate portion 21 and the riser portion 22 with the image 160.

Further, the image 160 is an image that gives an illusion of the position of the front edge portion 21b of the tread surface 21a, but is not limited to this. The image 160 may be an image that gives an illusion of the position of the rear edge portion 21c of the tread surface 21a.

Further, in the examples shown in FIGS. 6 and 7, the image 160 is illuminated by the tread 21 of the descending escalator 100, but the image 160 is not limited to this. Image 160 may be illuminated on the tread 21 of the ascending escalator 1. In this case as well, it becomes difficult for the user to grasp the positions of the front edge portion 21b and / or the rear edge portion 21c of the tread surface 21a, and it becomes difficult for the user to move on the tread 2. As a result, the movement of the user on the step 2 can be effectively suppressed.

Further, in the first and second embodiments described above, the lighting device 40 may illuminate the step 2 so as to match the three-dimensional shape of the step 2 by using the projection mapping technique. In this case, the above-mentioned illusion can be effectively generated for the user.
