Description

Embodiments of the present invention relate to escalators, particularly escalators with light source devices.

Conventionally, various measures have been taken to alert escalator users to their feet. For example, there are those that are colored to make it easier to recognize the boundary between the steps and the entrance, and those that are equipped with lighting near the comb. In addition, there is a structure in which light is applied from a truss under the steps so that the light leaks out from the boundary between adjacent steps.

In both cases, users are advised to pay attention to the steps that are moving in the direction of travel and the vicinity of the doorway that is fixed to the building.

From the standpoint of preventing shoes and clothes from getting caught in the step itself, the end of the step on the drag side is bordered with a highly visible yellow line, ie, a demarcation line. In addition to the colored ones, there are also those that have batteries and lights in the steps themselves, and that supply power from the provided batteries to illuminate part of the demarcation line.

In addition, since demarcation lines may be provided only in the three directions on the retracted side of the tread or may be provided in all four directions, either one of them must be selected. In the case of the three-way demarcation, in the vicinity of the boarding gate, that is, in the horizontal part of the escalator, the adjacent parts are different in color, such as yellow and black, so that it is easy to grasp the boundary between the steps. In the case of four-way demarcation, there is an advantage that the boundary between adjacent steps is difficult to visually recognize in the horizontal portion, while the end portion is easy to visually recognize in the inclined portion. In addition, by coloring the four directions in this way, the movement of the step can be recognized even from a distance on the inclined portion. In other words, it can be said that the three-way demarcation is effective in the horizontal portion, while the four-way demarcation is effective in the inclined portion.

In order to enjoy the benefits of both, it would be a strong visual effect if the visible color could be changed according to the movement of the escalator and the position of the steps. It is difficult to change the color to

Moreover, even if the light source is used to change the color, the step having a battery-powered structure requires that the escalator be stopped and replaced with another battery every time the battery is exhausted. Since the escalator steps have a structure that rotates in conjunction with the movement of the chain, it is difficult to directly supply power to the steps. In addition, if the color is changed depending on the location, light emission control for each step is required.

Therefore, in the present embodiment, it is not necessary to control each step, and the step has a demarcation line that changes the color visible to the user according to the location, especially the light emitted from each step. To provide an escalator capable of alerting users of This solves the problem of four-way demarcation, in which it is easy to see the edge of the step on the riser side on the slope, but it is difficult to see the boundary of each step on the horizontal portion because the front and rear boundaries are the same color. do. At the same time, by using a light source that can be supplied continuously, it is possible to attract the user's attention more visually.

In order to solve the above problems, the escalator of the embodiment is installed on a lower floor and an upper floor of a building, and includes a first horizontal portion provided on the lower floor and a second horizontal portion provided on the upper floor. and an inclined portion connecting the first horizontal portion and the second horizontal portion, and a plurality of steps connected in an endless manner are connected to the first horizontal portion and the second horizontal portion. a pair of left and right skirt guards provided along the running direction of the steps in the escalator running on the sloped portion; a light source device continuously provided between the left and right skirt guards to irradiate light; a light-receiving section provided on the side of the step to receive light emitted from the light source device, and a guide provided along the longitudinal direction of the step to transmit the light received from the light-receiving section and emit light. a light means, a transmission part provided by covering a part of the surface of the step with the light guide means, and allowing the color of the light emitted by the light guide means at the inclined part to be visible to the outside; By not providing a light source device at a position overlapping the nose line in the first horizontal portion and the second horizontal portion of the skirt guard, the first horizontal portion or the second horizontal portion A first demarcation part that is visible in different states depending on whether it is positioned on the slope or on the inclined part, and is provided on the other side of the step facing the first demarcation part, a second demarcation portion visually distinct from the first demarcation portion and constructed of colored cleats.

FIG. 3 is an enlarged perspective view of the step 30, and FIG. 4 is a plan view. The steps 30 are provided with a body portion necessary for running, which is a combination of a step plate 303 and a riser 304, and a demarcation portion 305, which is a guide display for the purpose of preventing the feet from getting caught.

The main body includes a footboard 303 on which a person sits, a riser 304 perpendicular to the footboard 303, a hollow support frame 306 to which the footboard 303 and the riser 304 are attached, and a pair of left and right support frames in front of the support frame 306. A front wheel 301 and a pair of left and right rear wheels 302 are provided behind a support frame 306 and run along each guide rail in the truss 12 . The treads 303 and risers 304 have a plurality of grooves called cleats. The cleats of the treads 303 are configured to engage the door combs 60, 62, and the cleats of the riser 304 engage the ends of the adjacent steps 30. configured to mate.

The demarcation part 305 is a line for making the boundary between the steps 30 conspicuous, and is provided along the edge of the step board 303 in four directions. By clarifying the demarcation, which is the boundary of the stepped portion, passengers are cautioned not to approach the clearance around the step 30 .

As shown in FIG. 4, the demarcation section 305 consists of a warning display section 305A and a warning line 305B. The warning display portion 305A is made of a cleat made of transparent resin, and is provided on the tread 303 including the corner where the tread 303 and the riser 304 are joined so as to extend to the end of the tread 303 in the longitudinal direction. . The warning line 305B is made of plastic and has a width of about 3 cm, and is composed of cleats colored in a highly visible color such as yellow or yellow-green. In the tread 304, one side of the warning line 305B facing the warning display portion 305A is colored differently, so that the boundary with the adjacent tread 30 can be easily recognized.

5 is an xx cross-sectional view of FIG. 3, and FIG. 6 is a yy cross-sectional view of FIG. As shown in FIGS. 5 and 6, the warning display portion 305A is composed of a transmission portion 307 made of transparent resin and an optical fiber 308 as a light guide plate. Further, the warning display portion 305A is opened as a light receiving portion so as to take in light from the end portion (see FIG. 6). Since the transmissive portion 307 is made of transparent resin, the optical fiber 308 can be seen through when the step 30 is viewed from above. The transmissive portion 307 may be colorless or colored as long as the color inside or on the opposite side of the warning display portion 305A can be transmitted to some extent. The optical fiber 308 has a structure in which the light received from the light receiving portion is diffused by total reflection or refraction and is transmitted by propagating from the side portion to the center portion of the step board 303 . emits light from the periphery of the When no light is taken in, the color of part of the riser 304 or the support frame 306 below the transmissive portion 307 becomes visible.

In this embodiment, the light emitted from the lighting device 45 of the skirt guard 44 is taken in from the light receiving portion to light up a portion of the footboard 303, that is, the warning display portion 305A. By changing the color of illumination of the illumination device 45, it is possible to change the color development of the warning display portion 305A. The color of the illumination may be set to, for example, yellow similar to that of the caution line 305B, or different white, red, blue, or the like.

Next, with reference to FIGS. 7 to 10, how light is introduced into the light-emitting portion of the illumination device 45 and the steps 30 during operation of the escalator 10 of the present embodiment will be described. It is assumed that the escalator 10 is operated to ascend, and passengers board the steps 30 from the platform 34 on the lower floor. Since the direction of operation is reversed as an operation, the description of the downward operation will be omitted.

7 to 10 are side views showing part of the escalator 10. FIG. 7 and 8 show the inclined portion, and FIGS. 9 and 10 show the horizontal portion. The lighting device 45 provided on the skirt guard 44 is positioned at least on the nose line of the step 30 in the inclined portion. The nose line is a running trajectory followed by the tip of the tread surface of the step 30 .

FIG. 7 shows that the light source is provided in a belt shape so that the illumination device 45 overlaps the nose line, and FIG. 8 shows an illumination lamp 45A that is the light source. The illuminating lamps 45A are provided continuously, ie, in a line, or intermittently, ie, in a spot as shown in FIG.

As described above, the warning display portion 305A of the step 30 emits light by taking in light from the illumination device 45, particularly at the inclined portion, during operation of the escalator 10 (see FIGS. 6 and 7). If the escalator 10 is in operation, the lighting device 45 is lit, so control of the lighting device 45, etc., is not necessary aside from the operation control.

In addition, as shown in FIG. 8, when spot-shaped illumination lamps 45A are provided in the longitudinal direction on the inclined portion, by making the intervals uniform, the warning display portion 305A is displayed on the step 30 during operation. It looks like it's blinking. It is desirable that the intervals between the illumination lamps 45A, which are light sources, are substantially equal, and in particular, that the length of one illumination lamp 45A and the distance from the tip of the illumination lamp 45A to the adjacent tip of the illumination lamp 45A are uniform. As a result, even if the step 30 is different, the warning display portion 305A will light up at the same timing.

Alternatively, the length of one spot of the illumination lamp 45A of the illumination device 45 and the interval between the spots may be narrowed as the inclined portion approaches the horizontal portion. By doing so, the speed that appears to be blinking on the steps 30 changes. By narrowing the length of one spot of the illumination device 45 and the interval between the spots, the speed at which light enters the warning display portion 305A changes without electronically sending a signal and the illumination device 45 remains lit. It is possible to make it appear as if it is blinking.

On the other hand, in the horizontal portion, it is desirable that the light source of the illumination device 45 is not continuously provided at the position overlapping the footboard 303 . In other words, the lighting device 45 is not provided in the horizontal portion, or the lighting device 45A is not provided, or the lighting device 45 is provided at a location away from the running track of the footboard 303 (see FIG. 9). 45 illumination lights 45A are provided intermittently (see FIG. 10). In this embodiment, the illuminating lamp 45A is continuously provided on the inclined portion, and the illuminating lamp 45A is not provided on the horizontal portion.

The warning display unit 305A takes in the light emitted from the illumination device 45 from the light receiving unit, shines through the optical fiber 308, and the illuminated light becomes visible through the transmission unit 307. FIG. Therefore, in the case where the main body of the illumination device 45 or the illumination lamp 45A is not provided, the light is not transmitted in the horizontal portion of the warning display portion 305A. Since the slanted portion becomes visible due to the transmission of light, the peripheral edge of the tread 303 develops color and functions as a four-way demarcation, while the horizontal portion is a three-way demarcation where the boundary between the adjacent treads 30 is easy to see. function as

When the lighting device 45 is provided at a place away from the traveling track, light is not transmitted in the horizontal portion, and the same merits as in the case where the lighting device 45 or the lighting lamp 45A is not provided are produced, but the feet when getting on and off are also improved. It is possible to illuminate

When the illumination lamp 45A is intermittently provided, light is transmitted even in the horizontal portion, but the intermittent, that is, blinking light reaches the eyes of the passenger, so that it is possible to call attention when getting on and off. The color of light emission in the horizontal portion is not limited to the same as that in the inclined portion, and may be different between the lower floor side of the horizontal portion and the upper floor side of the horizontal portion.

In addition, when a light source is provided at a position where light is transmitted, it is desirable to intermittently provide the illumination lamp 45A in the horizontal portion. If they are different, the boundary between adjacent steps 30 can be clearly visually recognized, so they may be provided continuously.

Not only in the horizontal part but also in the inclined part, the color of the illumination device 45 may be changed for each location such as the lower floor side, the center, and the upper floor side. Alternatively, it emits different colors depending on the direction of travel. Since the color of light emitted from the warning display portion 305A is not limited, it may or may not be the same color.

Thus, as shown in FIGS. 7 and 10, the warning display portion 305A located on the nose line of the step 30 is different from the other demarcation portions 305 in material and color, so that it is visually easy to understand.

In the horizontal part, the color of the boundary between the front and rear steps 30 is different, so that the boundary between the adjacent steps 30 is easy to grasp, and in the inclined part, the color is different from that of the riser 304 and the tread 303. Therefore, it is possible to take advantage of the four-way demarcation, which makes it easy to grasp the ends. Unlike the other demarcation section 305, it is not painted in yellow or the like in advance. Therefore, by changing the color of the light, it is possible to make the boundary of the steps 30 easy to confirm.

(Modified example of the lighting device of the skirt guard and the warning display part on the steps)
Modified examples of the illumination device 45 and the warning display unit 305A are shown below. 11 and 12 are other modified side views showing part of the escalator 10, and FIGS. 13 to 15 are modified plan views showing other forms of the steps 30. FIG.

FIG. 11 shows an escalator 10 provided with a wide lighting device 45. FIG. The illumination device 45 passes over at least the nose line of the steps 30 .

FIG. 12 shows an escalator 10 provided with a plurality of lighting devices 45. As shown in FIG. One of the lighting devices 45 is positioned so as to pass over the nose line of the step 30 , and the other is positioned so as to overlap the trajectory of the end of the step 30 on the retracted side.

As shown in FIG. 13 as a plan view, the demarcation section 305 is provided with a warning display section 305A having a transparent section 307 except for one side on the side of the step 30 that is pulled in. As shown in FIG. On the attracted side, a normal yellow demarcation line is provided as an alert line 305B. As a method of taking in light in FIG. 13, even if it is a method of taking in direct light from a wide range on the side of the step 30 as shown in the direction d1, light is taken in from the light receiving part from the riser 304 side as shown in the direction d2. It is also possible to take in the light and make it spread out in two directions.

In FIG. 14, a warning display portion 305A is provided at the long side of the step 30 on the riser 304 side and the retracted side, and a warning line 305B is used on the short side.

In FIG. 15, the demarcation section 305 consists of a warning display section 305A having transmission sections 307 in all four directions. As in FIG. 13, the light may be taken in either direction d1 from the side of the step 30 or direction d2 in which the light is received from the ends in the longitudinal direction and split in the middle.

As shown above, in any of FIGS. 13 to 15, at least one direction on the riser 304 side is the warning display portion 305A.

When using the step 30 of FIG. 13 or 15, the configuration of the lighting device 45 of FIG. 11 is used, and when using the step 30 of FIG. 14, the configuration of the lighting device 45 of FIG. It is possible to realize the configuration of the escalator 10 having the light warning display portion 305A.

Alternatively, a light source may be provided under the step 30 instead of the lighting device 45 of the skirt guard 44 to take in the light projected from inside the truss 12 . In this case, the step 30 has at least a transmission portion 307 from the lower portion to the upper portion of the riser 304 so that the light emitted within the truss 12 is transmitted and reaches the step plate 303 . It is more preferable if an optical fiber 308 and other light guide plates are provided together with the transmission portion 307 . Depending on the position of the light source, the intensity of light that can be emitted may vary, but it can illuminate a wide area and attract visual attention.

As described above, according to the embodiment of the present invention, by providing the lighting device 45 in the fixed portion of the escalator 10, power is continuously supplied and a warning display is performed on the steps 30 with light. becomes possible. As a result, it is possible to call attention to one's feet during driving, and to improve workability in electrical maintenance, since it is only necessary to inspect the lighting device 45 of the skirt guard 44 . In addition, by illuminating a portion of the demarcation portion 305 provided at the edge of the step 30 from the viewpoint of preventing the passenger from being pulled in, safety during boarding can be ensured. In addition, by changing the color of the light from the illumination device 45, the color of the riser 304 side, which is particularly conspicuous during boarding, of the demarcation portion 305, which is the boundary of the steps 30, can be changed to change the degree of alertness.

Further, by making the riser 304 and the demarcation unit 305 on the side of the attraction different, the demerits of the four-way demarcation can be eliminated. In the horizontal part where the passenger gets on the step 30, the boundary with the adjacent step 30 becomes clear, so the safety of the foot is ensured.
