Description

An embodiment of the present invention relates to an escalator, particularly an escalator having a light source device.

Conventionally, various measures have been taken to alert the users of the escalator to their feet. For example, some have a conspicuous coloring so that the boundary between the step and the entrance / exit can be easily recognized, and some have lighting near the comb. In addition, there are some that shine light from the truss under the step so that the light leaks from the boundary with the adjacent step.

In each case, the user is alerted to the step in the direction of travel and the area around the entrance / exit fixed to the building.

From the viewpoint of preventing shoes and clothing from being caught in the step itself, the end on the pull-in side is framed by a line such as yellow with high visibility, that is, a demarcation line. In addition to the colored ones, there are some that have a battery and a light on the step itself and illuminate a part of the demarcation line by supplying electric power from the provided battery.

In addition, the demarcation line may be provided in only three directions on the retracted side of the tread or in four directions in all directions, so it is necessary to select either one. In the case of three-way demaculation, the colors are different so that the adjacent parts are yellow and black in the vicinity of the entrance / exit, that is, in the horizontal part of the escalator, so that the boundary between the steps and the steps can be easily grasped. In the case of the four-way demaculation, there is an advantage that the boundary between adjacent steps is difficult to see in the horizontal portion, while the end portion is easily visible in the inclined portion. In addition, by coloring in four directions in this way, the movement of the step can be seen even from a distance in the inclined portion. That is, it can be said that the three-way demacation is effective in the horizontal portion, while the four-way demacation is effective in the inclined portion.

To enjoy both advantages, the visual effect is strong if the visible color can be changed according to the movement of the escalator and the position of the step, but the demarcation line painted in a specific color is in operation. It is difficult to change the color to.

Further, even when the color is changed by using a light source, it is necessary to stop the operation of the escalator and replace it with another battery every time the battery is consumed in the step where the electric power is supplied by the battery. Since the step of the escalator has a structure that rotates in conjunction with the movement of the chain, it is difficult to directly supply electric power to the step. In addition, if the color is to be changed according to the location, it is necessary to control the light emission to each step.

Therefore, in the present embodiment, it is not necessary to control each step, and the passenger is riding through a step having a demarcation line whose visible color changes depending on the location, particularly a light emitted from each step. The purpose is to provide an escalator that can alert the users of. This solves the difficulty of four-way demaculation that it is easy to grasp the end of the step on the riser side in the inclined part, but it is difficult to grasp the boundary of each step because the color of the front and rear boundaries is the same in the horizontal part. do. At the same time, by using a light source that can be continuously supplied, it is possible to attract the user's attention more visually.

In order to solve the above problems, the escalator of the embodiment is erected on the lower floor and the upper floor of the building, and the first horizontal portion provided on the lower floor and the second horizontal portion provided on the upper floor.

In the latter case, an LED lamp formed from a dot matrix arranged in a grid pattern may be used. The illuminating lights of the illuminating device 45 are arranged in a line shape or in a plurality of spots at intervals. When the escalator 10 is in operation, the illumination lamp is turned on.

FIG. 3 is an enlarged perspective view of the step 30, and FIG. 4 is a plan view. The step 30 includes a main body portion necessary for traveling by combining the tread plate 303 and the riser 304, and a demacation portion 305 which is a guidance display for the purpose of preventing the feet from being caught.

The main body has a tread 303, which is a part on which a person rides, a riser 304 perpendicular to the tread 303, a hollow support frame 306 to which the tread 303 and the riser 304 are attached, and a pair of left and right on the front part of the support frame 306. A front wheel 301 and a pair of left and right rear wheels 302 are provided behind the support frame 306, and the vehicle travels along each guide rail in the truss 12. The tread 303 and the riser 304 have a plurality of grooves called cleats, the cleats of the tread 303 are configured to mesh with the combs 60 and 62 of the entrance / exit, and the cleats of the riser 304 are connected to the end of the adjacent step 30. It is configured to engage.

The demacation portion 305 is a line for conspicuous the boundary between the step 30 and the step 30, and is provided around the end portion of the tread 303 in four directions. By clarifying the demacation that is the boundary of the step portion, caution is drawn so that passengers do not approach the gap at the periphery of the step 30.

As shown in FIG. 4, the demacation unit 305 includes a warning display unit 305A and a warning line 305B. The warning display unit 305A is made of a transparent resin cleat, and is provided on the tread plate 303 including a corner portion where the tread plate 303 and the riser 304 are bonded so as to extend to the longitudinal end portion of the tread plate 303. .. The alert line 305B is made of plastic with 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 alert line 305B facing the warning display unit 305A has a different color scheme, so that the boundary with the adjacent tread 30 can be easily understood.

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

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

Next, with reference to FIGS. 7 to 10, a method of taking in light at the light emitting point of the lighting device 45 and the step 30 during the operation of the escalator 10 of the present embodiment will be described. It is assumed that the escalator 10 is operated ascending, and that passengers board the step 30 from the boarding / alighting board 34 on the lower floor. Since the direction of operation is only opposite as the operation, the description of the descending operation will be omitted.

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

FIG. 7 shows that the light source is provided in a band shape so that the lighting device 45 overlaps the nose line, and FIG. 8 shows a lighting lamp 45A which is a light source. The illuminating lamp 45A is provided continuously, that is, in a line shape, or intermittently, that is, in a spot shape, as shown in FIG.

As described above, the warning display unit 305A of the step 30 takes in light from the lighting device 45 and emits light during the operation of the escalator 10, especially in the inclined portion (see FIGS. 6 and 7). Since the lighting device 45 is lit while the escalator 10 is in operation, it is not necessary to control the lighting device 45 separately from the operation control.

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

Alternatively, the length of one spot of the illuminating lamp 45A of the illuminating device 45 and the distance between the spots may be narrowed as the inclined portion approaches the horizontal portion. In this way, the speed at which the step 30 appears to be blinking changes. By narrowing the length of one spot of the lighting device 45 and the interval between the spots, no signal is sent electronically, the lighting device 45 remains lit, and the speed at which light enters the warning display unit 305A changes. It is possible to make it appear to be blinking.

On the other hand, in the horizontal portion, it is desirable that the light source of the lighting device 45 is not continuously provided at a position overlapping the tread 303. That is, the lighting device 45 is not provided in the horizontal portion, or the lighting device 45A of the lighting device 45 is not provided, and the lighting device 45 is provided in a place off the traveling track of the tread 303 (see FIG. 9). It is desirable that the lighting 45A of 45 is provided intermittently (see FIG. 10). In the present embodiment, the illuminating lamp 45A is continuously provided in the inclined portion, and the illuminating lamp 45A is not provided in the horizontal portion.

The warning display unit 305A takes in the light emitted from the lighting device 45 from the light receiving unit and shines through the optical fiber 308, so that the lit light can be visually recognized from the transmission unit 307. Therefore, if the lighting device 45 main body or the lighting 45A is not provided, the warning display unit 305A does not transmit light in the horizontal portion. Since light is transmitted in the inclined portion to make it visible, the peripheral edge of the tread 303 develops color and functions as a four-way demacation, while in the horizontal portion, the boundary with the adjacent tread 30 is easily understood as a three-way demacation. Functions as.

When the lighting device 45 is installed in a place off the traveling track, light is not transmitted in the horizontal portion, and the same merit as when the lighting device 45 or the lighting light 45A is not provided is obtained, and the feet when getting on and off are provided. It is possible to illuminate.

When the lighting 45A is provided intermittently, the light is transmitted even in the horizontal portion, but the intermittent, that is, the blinking light reaches the passengers' eyes, so that attention can be drawn when getting on and off. The color of the light emitted 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 provide an illumination lamp 45A intermittently in the horizontal portion, but the color emitted from the light source is the caution line 305B, that is, a yellow demacation. If they are different, the boundary with the adjacent step 30 can be clearly seen, so that they may be provided continuously.

The color of the lighting device 45 may be changed not only in the horizontal portion but also in the inclined portion for each place such as the lower floor side, the center, and the upper floor side. Alternatively, it emits a different color depending on the direction of operation. Since the color of the light emitted from the warning display unit 305A is not limited, it may or may not be the same color.

As described above, as shown in FIGS. 7 and 10, the warning display unit 305A located on the nose line of the step 30 is visually easy to understand because the material and color are different from those of the other demaculation units 305.

In the horizontal part, the borders of the front and rear steps 30 are different in color, so it is easy to grasp the boundaries between the adjacent steps 30. In the inclined part, the colors are different from those of the riser 304 and the tread 303. Therefore, it is possible to take advantage of both sides of the four-way demacation, which makes it easy to grasp the edges. Unlike the other demaculation unit 305, it is not painted in yellow or the like in advance, so it is possible to easily confirm the boundary of the step 30 by changing the color of the light.

(Modification example of warning display part in skirt guard lighting device / step)
Hereinafter, a modified example of the lighting device 45 and the warning display unit 305A will be shown. 11 and 12 are modified examples of other side views showing a part of the escalator 10, and FIGS. 13 to 15 are modified examples of a plan view showing another form of the step 30.

FIG. 11 is an escalator 10 provided with a wide lighting device 45. The illuminating device 45 passes at least on the nose line of the step 30.

FIG. 12 is an escalator 10 provided with a plurality of lighting devices 45. Regarding the lighting device 45, one is arranged at a position where it passes on the nose line of the step 30, and the other is arranged at a position where it overlaps with the track of the end of the step 30 on the retracted side.

As shown in FIG. 13 as a plan view, the demacation unit 305 is provided with a warning display unit 305A provided with a transmission unit 307 except for one direction on the retracted side in the step 30. The pull-in side is provided with a normal yellow demarcation line as a warning line 305B. As for the method of taking in the light in FIG. 13, even if the method of taking in the light directly from a wide range on the side of the step 30 as shown in the direction d1, as shown in the direction d2, from the light receiving portion from the riser 304 side. You may take in the light and spread it in two hands.

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

FIG. 15 is composed of a warning display unit 305A having a transmission unit 307 in all four directions of the demacation unit 305. As in FIG. 13, the light may be taken in in the direction d1 from the side of the step 30 or in the direction d2 in which the light is received from the end portion in the longitudinal direction and split into two hands 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 unit 305A.

When the step 30 of FIG. 13 or 15 is used, the configuration of the lighting device 45 of FIG. 11 is used, and when the step 30 of FIG. 14 is used, the configuration of the lighting device 45 of FIG. 11 or FIG. 12 is used. It is possible to establish the configuration of the escalator 10 having the light warning display unit 305A.

Another method is to provide a light source under the step 30 instead of the lighting device 45 of the skirt guard 44 as a light source and take in the light projected from the inside of the truss 12. In this case, there is at least a transmitting portion 307 from the lower part to the upper part of the riser 304 in the step 30 so that the light emitted in the truss 12 is transmitted and the light reaches the tread 303. It is even better to have an optical fiber 308 and other light guide plates together with the transmissive portion 307. Depending on the position of the light source, the intensity of the light that can be emitted may change, but the light can be lit in a wide range and can 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, a warning display by light is performed on the step 30 while continuously supplying electric power. It becomes possible. As a result, it is possible to promote the attention of the feet during operation and improve the workability because the lighting device 45 of the skirt guard 44 may be inspected for electrical maintenance. Further, from the viewpoint of preventing pulling in, by illuminating a part of the demaculation portion 305 provided on the edge of the step 30, safety during riding can be ensured. In addition, it is possible to change the degree of attention by changing the color of the light of the lighting device 45 on the color of the riser 304, which is particularly conspicuous during riding, among the demaculation unit 305 which is the boundary in the step 30.

Further, by making the riser 304 and the demacation unit 305 on the pull-in side different configurations, the demerit in the four-way demacation can be eliminated. In the horizontal portion where passengers board the step 30, the boundary with the adjacent step 30 becomes clear, so that the safety of the feet is ensured.
