Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a passenger conveyor,
In particular, the present invention relates to a passenger conveyor that can ensure the safety of passengers in a boarding / alighting section.

[0002]

2. Description of the Related Art Generally, each elevating port of an escalator is provided with a comb plate that engages with the surface of a moving tread. This comb plate is designed to safely raise and lower passengers.

Conventionally, as disclosed in Japanese Utility Model Application Laid-Open No. 60-133573, a passenger conveyer is proposed, which is formed of a light-transmitting body and has a light source and an optical fiber for guiding the light generated by the light source to the comb plate. Has been done.

[0004]

In the above prior art, since the light is guided from the light source to the comb plate by the optical fiber, the optical fiber is embedded in the lower surface of the comb plate mount. Therefore, the cost of the optical fiber and the cost of comb plate processing are high, and the device becomes expensive, and when repairing or replacing the optical fiber or light source, a narrow machine installed under the boarding / alighting section There was a problem of maintainability such that it took time and labor to enter the room and work.

An object of the present invention is to provide a passenger conveyor which can sufficiently alert the passengers when getting on and off, is inexpensive and has excellent maintainability.

[0006]

In order to achieve the above-mentioned object, the present invention is endlessly connected and fixed to a large number of steps provided with surface cleat grooves and a comb plate mount of a boarding / alighting section. In a passenger conveyor provided with a comb plate, at least a part of the comb plate is formed by a light transmitting body, and a light source for causing the comb plate to emit light is provided on a lower surface of the comb plate mount. ..

[0007]

Since the present invention is configured as described above, the light emitted from the light source installed on the lower surface of the comb plate mount passes through the gap between the comb plate mount and the step while the passenger conveyor is driven, Light can be emitted from the light-transmitting body of the comb plate, and the light source mounted on the comb plate mount can be easily replaced by simply opening the door cover without entering the machine room, making it an inexpensive and highly maintainable device. It can alert passengers.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

In the figure, 1 is a moving handrail, 2 is a balustrade for holding the moving handrail 1, 3 is a step for moving in synchronization with the moving handrail 1, 4 is a comb plate provided at the entrance / exit, and this comb plate 4 The tooth portion 4a side is formed of, for example, a light-transmitting body 4b colored in green, and the attachment portion 4c side has a mounting hole 4d fixed to the comb plate mounting base 5. In addition, steps 3a to 3c in the lower surface of the comb plate mount 5 and the boarding / alighting section
The distance d from the upper surface of is about 5 mm. Reference numeral 6 denotes a light source composed of a plurality of light sources that cause the light transmitting body 4b to emit light.
Is installed on the lower surface entrance / exit cover 7 side and has a reflecting mirror 6b on the opposite side of the light source 6 from the comb plate 4.
The luminous efficiency to the side is improved. It should be noted that the light source 6 is adapted to be turned on in conjunction with the activation of the passenger conveyor. The light source 6 is attached to the cover 6c and can be rotated by a hinge 6d.

In the embodiment constructed as described above, the light source 6 is turned on in association with the activation of the passenger conveyor, and the white light 6a generated by the light source 6 and the lower surface of the comb plate mounting base 5 and the steps 3a to 3c. The light transmitting body 4b of the comb plate 4 is lit by the white light 6a. By lighting the comb plate 4 in this way, a passenger who is about to get on or off the step 3 can recognize the position of the entrance / exit. Also,
If you open the door cover 7 and rotate the cover 6c,
The light source 6 can be easily replaced at the entrance / exit even if it does not enter a machine room (not shown) and can be replaced by a broken ball or cleaned.

In the above-described embodiment, the light source 6 is made to emit white light 6a. However, the present invention is not limited to this, and the light source 6 may emit red light, green light, or the like. Good. Further, although the light transmitting body 4b is formed on the tooth portion 4a side of the comb plate 4, the whole comb plate 4 may be formed of the light transmitting body 4b.

In the above-described embodiment, the light source 6 is turned on in synchronization with the activation of the passenger conveyor. However, if the light source 6 blinks in synchronism with the moving speed of step 3, the passenger can get on and off more reliably. The position of can be recognized.

[0013]

According to the present invention, when the passenger conveyor is driven, the light emitted from the light source installed on the lower surface of the comb plate mount passes through the gap between the comb plate mount and the step,
Light can be emitted from the comb plate and the light transmitting body, and the light source can be easily replaced by simply opening the entrance / exit cover, so that the passenger can be alerted with an inexpensive and highly maintainable device.
