Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a passenger conveyor such as an escalator or an electric road, and particularly to a display device in a handrail portion.

In general, the performance required of a passenger conveyor is not only transportation capacity and safety, but also economic efficiency through power saving measures, design that harmonizes with architectural design, and maintainability that directly leads to reduction of overall management costs. There are a wide variety of items such as: Naturally, new technologies that achieve these various items are in high demand, and their superiority or inferiority is important in determining their product value.

[Background of the invention]

As shown in Figures 1 to 3, a conventional passenger conveyor consists of a step 1 that is arranged in an endless manner to carry each user, a rotating body such as a handrail 2, and an inner deck 4% that constitutes a handrail 3. It is made up of fixed bodies such as an outside deck 5, a glass panel 6, a handrail frame 7, an openable floorboard 8 with floor letters 8a, and a machine room 8b that stores machinery below, and these three railings are the main parts. It is a design range.

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.

In other words, the end of the parapet 3 (near the passenger conveyor entrance)
(1) Please stand in the center of the steps.

(2) Children should hold their hands when riding.

(3) Please hold on to the handrail.

Caution name plate 1 with precautions for using the passenger conveyor, such as
2, or broadcasting device 1 that broadcasts usage precautions in audio
3 and other software safety services are installed, while Takumi 14 also installed safety equipment for the safety equipment in case a foreign object is drawn into the entrance of the safety rail, and a skirt guard on the side of Step 1. A skirt guard safety device 15 is provided in case a foreign object is pulled in, an emergency stop device 16 is used to suddenly stop the operation of the passenger conveyor, and a loading board 17 is used to prevent foreign objects from entering the outer deck 5. - Also installed are devices that provide advanced safety services.

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 appeal is 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) If a foot gets caught between Step 1 and the skirt guard on the side of Step 1, it will cause a serious accident, so this device detects the initial phenomenon of this and stops the operation of the passenger conveyor. . As shown in FIG. 4, the details are that the microswitch 18 operates when the skirt guard is pushed by a foreign object and deforms as shown by the two-dot chain line. In addition to the skirt guard safety device 15, the passenger conveyor has a handrail safety device 14, and although the illustrations may be omitted, there are many other devices inside the passenger conveyor, such as a step abnormality detection device, a drive chain abnormality detection device, and a step chain safety device. Safety equipment is in place.

(2) A problem not limited to this microswitch 18 but common to all safety devices is that when restarting the operation of a passenger conveyor that has stopped due to some reason, it is difficult to make a decision. That is, this skirt guard safety device 1
In cases such as No. 5, the operation factor is due to the influence of passengers' feet or foreign objects, and if this factor is removed, it is possible to visually check and start operation immediately. However, if the step chain safety device housed inside the passenger conveyor is activated and the vehicle is stopped, the driver will encounter even more serious trouble when returning home. For this reason, determining whether to resume operation of a conventional passenger conveyor requires an internal inspection by a specialized maintenance person, which naturally lengthens the downtime.

3. Regarding the partition plate 17.

(1) This is a board to prevent children who play on the deck 5, such as a slide, or who enter the deck 5 from an upper floor, from falling.

(2) It is a completely different part from the equipment of passenger conveyors that are used for transportation, and 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, passengers are distracted by the attention plate 12 and floor letters 8a and the broadcasting device 13, and their attention is distracted.

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 was also pointed out that the driving direction of the passenger conveyor cannot be determined from a distance, which is inconvenient, and the design is lacking, such as the lack of variation in the overall design of the passenger conveyor.
