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 energy saving, 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 desired, and their superiority or inferiority has become important in determining commercial value.

[Background of the invention]

As shown in Figs. 1 to 3, a conventional passenger conveyor has steps 1 arranged in an endless manner to carry passengers, rotating bodies such as handrails 2, and an inner deck 4 forming a parapet 3. It is made up of fixed bodies such as an outer deck 5, a glass panel 6, a handrail frame 7, and a floorboard 8 with floor letters 8a, and these 3 parts of the handrail are the main design area.
Further, near the upper part of this balustrade 3, a balustrade illumination device 11 composed of a lamp 9 and a lighting cover 10 is arranged, and is designed 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, at the end of handrail 3 (near the entrance to the passenger conveyor): (1) Please step in the center of the steps.

(2) Please hold your child's hand when riding.

(3) Please hold on to the handrail.

At the entrance of the handrail, there are equipment that provides soft safety services, such as a caution plate 12 with precautions for use of the passenger conveyor, and a broadcasting device 13 that broadcasts precautions in audio. A handrail safety device 14 in case a foreign object is drawn in, a skirt guard safety device 15 in case a foreign object is drawn in between the skirt guard on the side of step 1, and an emergency device to suddenly stop the operation of the passenger conveyor. Devices that perform hard safety services, such as a stop device 16 and a loading plate 17 that prevents entry into the outer deck 5, are also installed.

Here, we will explain (1) the reason and function of each of the conventional safety devices mentioned above, and (2) room for improvement (defects).

1 Regarding caution plate 12.

(1) The majority of personal accidents on passenger conveyors are caused by carelessness when using the conveyor, 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 where you step 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. . The details are as shown in FIG. 4, when the skirt guard is pushed by a foreign object and deformed as shown by the two-dot chain line, the micro switch 18 operates. In addition, this skirt guard safety device 1 is installed on the passenger conveyor.
In addition to the safety device 5, a large number of safety devices such as a handrail safety device 14, a step abnormality detection device, a drive chain abnormality detection device, and a step chain safety device are arranged inside the passenger conveyor, although their illustrations may be omitted.

(2) A problem not limited to this micro switch 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,
The operation factor of the skirt guard safety device 15 and the like is due to the influence of passengers' feet and foreign objects, and if this factor is removed, operation can be started immediately after visual confirmation. 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,
Judging whether to resume operation of a conventional passenger conveyor requires internal inspection by dedicated maintenance personnel, 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 for transportation purposes, 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 lose their attention because they are distracted by the caution signboard 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 points, conventional passenger conveyors have disadvantages in terms of use, such as the inconvenience of not being able to judge the driving direction of the passenger conveyor from a distance, and design issues, such as the lack of change in the overall design of the passenger conveyor. It has also been pointed out that it is lacking.

[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.

[Summary of the invention]

Steps forming an endless track between the entrance and exit, and steps provided along both sides of the upper track portion of the endless track, and at least wall portions near the entrance and exit are constructed of glass panels. A handrail and a message reminding passengers to be careful when getting on and off the train.
A driving direction display, a store name display, and a safety device operating status display are provided on a display surface in which they are written in the order from the top to the bottom, and the display surface is placed on the glass panel on the non-step side of the parapet. and a display device disposed toward the camera.
