In general, the performance required of a passenger conveyor is not only transportation capacity and safety, but also economic efficiency through energy saving, design that harmonizes with architectural design, and maintenance that directly introduces reduction of overall management costs. There are a wide variety of items such as gender. Naturally, new technologies that achieve these various items are desired, and their superiority or inferiority is important in determining commercial value.

[Background of the invention]

A conventional passenger conveyor has a through hole shown in FIGS. 1 to 3, stems 1 that are arranged in an endless manner to carry passengers, rotating bodies such as handrails 2, and an inner deck 4 that constitutes a handrail 3. , the main design area is the 3 parts of the railing, which is made up of fixed bodies such as the outer deck 5, the glass panel 6, the handrail frame 7, and the floorboard 8 with floor letters 8aTh.

Further, a balustrade lighting device 11 composed of a lamp 9 and a lighting cover 10 is arranged near the top of the balustrade 3, and is configured to emit illumination light K over the entire length of the passenger conveyor.

The above is the configuration of the balustrade 3 which mainly focuses on the design aspect, but this balustrade 3 is also an important device for ensuring safety.

3 and other soft safety services are installed, while -. In case a foreign object is drawn into the entrance of the rail, there is a safety device 14 between the rail safety device 14 and the skirt guard on the side of step l. Foreign object? There are also devices that perform safety services such as a skirt guard safety device 15 in case of retraction, an emergency stop device 16 that suddenly stops the operation of the passenger conveyor, and a loading board 17 that prevents entry into the outer deck 5. installed.

Here, we will discuss typical examples of each of the conventional safety devices mentioned above (
Explain 1) the reason and function of the equipment, and (2) room for improvement (deficiencies).

1. Regarding caution plate 12.

(1) The majority of personal accidents on passenger conveyors are caused by carelessness during use, and as a preventive measure, visual appeals are used to call attention to this.

(2) When getting on and off, you need to be careful about your feet because you move from the fixed floor plate 8 to the rotating step 1, but if you get distracted by the caution plate 12, you may fall.

2. Regarding the skirt guard safety device 15.

(1) A device that detects the initial phenomenon of this and stops the operation of the passenger conveyor because if a foot gets caught between this step 1 and the skirt guard at the first wound in step 1, it will cause a serious accident. It is. The details are that the microswitch 18 operates when the pass and skirt guard shown in FIG. 4 is pushed by a foreign object and deformed as shown by the two-dot chain line. In addition,
In addition to the skirt guard safety device 15, the passenger conveyor includes a handrail safety device 14 and a number of safety devices such as a step abnormality detection device, a drive chain abnormality detection device, a step chain safety device, etc. (not shown) inside the passenger conveyor. has been placed.

(2) A problem not limited to this micro-sinch 18 but common to all six safety devices is that when restarting the operation of a passenger conveyor that has stopped due to some reason, a situation arises in which it is difficult to make a decision. That is, the operation factors of the skirt guard safety device 15 and the like are due to the influence of passengers' feet and foreign objects.1.If this factor is removed, it is possible to visually check and immediately start operation. However, if the step chain safety device housed inside the passenger conveyor is activated and the conveyor is stopped, resuming operation will cause even more serious trouble. For this reason, determining whether to restart operation of conventional passenger conveyors requires an internal inspection by specialized maintenance personnel.
Naturally, the downtime will be longer.

3. Regarding the partition plate 17.

(1) It was on the outside deck 5. After playing like a bench, I entered the outside deck 5 from the upper floor. This is a board to prevent children from falling.

(2) It is a completely different part from the equipment of passenger conveyors that are used for transportation, and 1. There is an undeniable sense of incompatibility in terms of design and function.

A summary of what has been said above is as follows.

(1) During boarding and alighting operations that require careful attention, a passenger's attention is distracted by the attention plate 12 and floor letters 8a and the broadcasting device 13.

As a result, there is a concern that this may lead to troubles such as falling.

2. When restarting the operation of a passenger conveyor that has been stopped due to the operation of a safety device, it takes time to judge the status of the safety device inside the passenger conveyor.

3. The presence of the partition plate does not match the overall design of the passenger conveyor.

Furthermore, in addition to these three items, with conventional passenger conveyors,
It has also been pointed out that the driving direction of the passenger conveyor cannot be determined from a distance, which is inconvenient, and that the design is unsatisfactory, such as the lack of variation in the overall design of the passenger conveyor.

[Purpose of the invention]

In view of this, the present invention has been made to provide a balustrade configuration that increases passenger safety by providing a multi-purpose display device on the balustrade, particularly near the entrance/exit.

A moving step, a le hunt rail that rotates synchronously with this step, located between this step and the hand rail,
For railings made of glass panels, external decks, etc., and equipped with various safety devices, the railing near the entrance/exit,
The means for displaying cautions on the passenger conveyor and the means for displaying the operation of the safety device are performed by a display device composed of a light emitting body.

[Embodiments of the invention]

Hereinafter, one embodiment of the present invention will be described based on the drawings.

In FIGS. 5 and 6, the rotating bodies such as the step 1 and the end rail 2, the glass panel 6, the end rail frame 7, etc. are the same as those in the prior art, but in the present invention, they are in contact with the glass panel 6. The present invention is characterized by the provision of a display device 19 provided on the lower side of the glass panel, and an output device 21 for the display device 19 provided below the outer deck 20 on the lower side of the glass panel.
