Abstract

PROBLEM TO BE SOLVED: To make the timing of footsteps on a moving a staircase easily takable by generating a pulse signal to synchronize with a travel speed of this moving staircase, and illuminating each of stair treads of the moving staircase on the basis of a signal out of a pulse signal generating means installed by way of facing to this staircase. SOLUTION: Simultaneously with the operation start of an escalator, a pulse signal synchronized with each travel speed of three moving stairs 3, 3a and 3b is outputted from a speed detector 10 installed in a shaft end of a driving machine 6, and then it is converted into the specified pulse voltage in a control transmitting part 11, supplying it to an illuminant power supply part 12, and flashing voltage is fed to each illuminant 13 at both sides, making it be lighted at the specified interval. This light is emitted on a conductive optical path of an optical fiber 14 at each position of these stairs 3, 3a and 3b in synchronizing three spherical light emitting parts 15, 15a and 15b being opposed with one another as holding the moving staircase between. Accordingly, individual passengers adjust the stairs 3, 3a and 3b emerging from the underside of a lifting plate 9 to each emission of the light emitting parts 15, 15a and 15b and their foots are stepped thereon, whereby they can take the timing of footsteps in an easy manner.

[0003] In such a structure, normally, in the ascending operation, the passenger steps on the moving step 3 which is cyclically moving from the lower entrance 2 while grasping the moving handrail 8 which is moving synchronously, and gets on the vehicle. It At that time, the passenger gets into the moving step 3 while paying attention to the boundary so that the front and rear of the moving step 3a at the front stage and the moving step 3b at the rear side, which determine the moving step 3, are not caught. If it makes a difference,
Since the center of gravity of the passenger tilts and becomes unstable, the passenger will simultaneously grasp the moving handrail 8. Further, since the moving steps 3 and the like are continuously moving, if the foot is dark but the eyes are visually impaired or the eyes are visually impaired, the passenger cannot easily see the above-mentioned eyes. You will get on the moving step 3 relying on the light of 9a.

Further, as a moving step display device for guiding passengers from such a boarding / alighting gate, for example, an actual Kaihei 2-97 is conventionally used.

Japanese Patent No. 7 discloses a balustrade panel near an entrance / exit of a parapet that displays an arrow or a character for guiding passengers.

[0005]

However, in the conventional moving step display device as described above, since the display device is provided at the upper part of the entrance / exit and the side surface of the balustrade panel, it is not possible to use the same as the illuminated tread surface. There is a problem in that the eyes of the passengers do not match and it is difficult for the passengers to step on the moving step.

The present invention has been made in order to solve such a problem, and it is possible to easily set a timing at which a passenger steps on a moving step and to effectively guide the passenger to the moving step. An object is to provide a display device.

Is a speed detector that generates a pulse signal in synchronization with the moving speed of the vehicle. The pulse signal from the speed detector 10 is supplied to the control transmission unit 11 in the controller 7A and converted into a pulse voltage having a predetermined interval. The pulse voltage from the control transmission unit 11 is also supplied to the light source power source unit 12 in the controller 7A, and is supplied from the light source power source unit 12 to the light source 13 as a power source having a substantially blinking voltage. The light sources 13 are attached to the lower portions of the inner deck covers 5 on both sides.

Reference numerals 14 and 15 are provided in the space portions 5a inside the inner deck covers 5 on both sides, respectively, for guiding the light from the light source 13 and emitting the luminous flux, 15, 1
Reference numerals 5a and 15b denote spherical light emitting portions which are provided on the light guide paths of the optical fibers 14 on both sides so as to face each other with the moving steps 3, 3a and 3b interposed therebetween and which are provided at a constant interval. As the spherical light emitting portions 15, 15a, 15b, those formed by branching the optical fiber 14 are used. The optical fiber 14, the spherical light emitting portion 15 and the like are supported by a supporting member 5b in a space 5a inside the inner deck cover 5. 1
Reference numeral 6 denotes a light-transmitting portion made of, for example, an acrylic plate or a glass plate, which is arranged on the surface of the inner deck covers 5 on both sides along the moving direction of the moving steps 3. It should be noted that the speed detector 10 and the control transmitter 11 constitute a panel generating means, and the light source 1
3, the fiber 14, the spherical light emitting portion 15 and the like constitute a light emitting means.

Next, the operation of the first embodiment of the present invention will be described with reference to FIGS. 3 and 4. The speed detector 1 provided at the shaft end of the driving machine 6 when the operation of the escalator starts.
From 0, a pulse signal synchronized with the moving speed of the moving steps 3, 3a, 3b is output. This pulse signal is supplied to the control transmission section 11 in the controller 7A, converted into a pulse voltage having a predetermined interval and supplied to the light source power supply section 12,
As a result, the light source power supply unit 12 is energized. Then, the light source power source unit 12 supplies the blinking voltage as a power source to the light sources 13 on both sides, and lights it at a predetermined interval.

The light emitted from the light source 13 is turned on by the optical fiber 1.
4 is guided and emitted along a light guide path. Then, the moving steps 3, 3a, 3b are placed on the light guide path of the optical fiber 14.
The spherical light emitting portions 15, 15a, 15b, which are opposed to each other with the light beam interposed therebetween and are provided at a constant interval, simultaneously emit light. That is, the spherical light emitting parts 15, 15a, 15b substantially facing the moving steps 3, 3a, 3b respectively emit light simultaneously at the positions of the moving steps 3, 3a, 3b in synchronization with the moving speed of the moving steps. Therefore, the passenger can move the moving steps 3, 3a, 3b appearing from the lower side of the elevating plate 9 into the spherical light emitting parts 15, 1
It suffices to step on each of them according to the light emission of 5a and 15b, provided that the moving steps 3, 3a and 3b are in progress while the light is extinguished.
This is the position where the tread of is not fully exposed.

Since the moving steps 3, 3a and 3b are continuously moving, the tread surface of one moving step is the boarding / alighting plate 9a.
For example, the corresponding spherical light-emitting portion is made to emit light at about half or more, and when the tread surface of the rear moving step starts to come out of the boarding / alighting board 9, the spherical light-emitting portion that is emitting light is extinguished, and the moving step at the rear step is also made again. When the tread surface is about half way out of the boarding / alighting plate 9, the corresponding spherical light emitting portion is caused to emit light, and the pulse is outputted in advance from the control transmitting portion 11 so that the other spherical light emitting portions can similarly control the light emission. Set the voltage in advance.

As described above, in the present embodiment, at least the tread surface of at least three steps, for example, three steps counted from the boarding / alighting plate is illuminated in the moving direction of the moving step, and light is emitted in the vicinity of the line of sight of the tread surface on which the passenger steps. Therefore, the tread surface of the illuminated moving step and the line of sight of the passengers coincide with each other, and the timing of stepping on the moving step can be easily taken.
It is possible to effectively guide the passenger to step on the moving step. Further, since the steps in the line-of-sight direction of the passengers are illuminated in succession one after another in synchronization with the moving speed of the moving steps, the steps are brighter than before and the passengers can easily get on the moving steps.
