Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a safety device for escalators, and is particularly suitable for use in narrow corners where the ceiling of a building and an escalator or an ascending escalator and a descending escalator intersect closely. Regarding safety equipment.

[Conventional technology]

Escalators are required to be absolutely safe as public transportation, and the areas around their rotating parts, especially the steps and handrails directly used by passengers, are designed with the utmost care to improve safety. has been done. Under these circumstances, safety equipment has recently been used around the escalator itself, such as fall prevention shelves on the upper floor of the escalator and the triangular intersection formed between the escalator and the building ceiling. .

As a typical example of conventional triangular intersections,
There are safety facilities as shown in Figure 2. This consists of a rotating endless step 1, a handrail 2, a handrail 3 that guides the handrail as it moves,
A triangular protection plate 6 suspended by a chain is provided at the triangular intersection between the escalator 4 and the building ceiling 5. Here, to explain the function of the protection plate 6 in detail, when a passenger leans out to the outside of the escalator, the ceiling 5 and the handrail 2
caught between. In order to prevent this in advance, the protection plate 6 is used to warn passengers. However, if the passenger is looking down, they will not notice until they hit the protection plate 6, and in this case, the protection plate 6 may be small or
If passengers were too late to escape, there was a risk of being trapped. There is also a method of operating a switch to stop the escalator when it hits the protection plate 6, but this method has the disadvantage of causing inconvenience to other passengers.

In order to eliminate the above-mentioned drawbacks, it has been proposed to provide a marker light that is constantly lit or flashing on the front surface of the protection plate, as described in Japanese Utility Model Application No. 54-105488.

[Problem that the invention attempts to solve]

In the above-mentioned proposed embodiment, since the marker light is always on or flashing, there is a problem that the effect becomes less effective as the user gets used to it.

The purpose of the present invention is to obtain a danger indicator light that will not lose its effectiveness.

[Means for solving problems]

The above purpose is to provide a human body detection device on the handrail portion at a forward position outside the handrail and sufficiently far away from the protection plate to detect a person leaning out from the handrail; This is achieved by turning on the marker light attached to the protection plate by the activation of the detection device.

[Effect]

The marker light provided in front of the protection plate is designed to light up only when the human body detection device provided in front of the protection plate is activated. This allows passengers to recognize that they are doing something dangerous and to retreat. In addition, since the light only lights up when a dangerous act occurs, its effectiveness as a danger indicator light will not be diminished.

〔Example〕

An embodiment of the present invention will be described below with reference to FIG. In the figure, the same reference numerals as in FIG. 2 indicate the same parts.

Reference numeral 7 denotes a transparent cylindrical body provided in front of the protection plate 6, and a marker light 8 is built into this cylindrical body 7.

Reference numeral 9 denotes a human body detection device installed on the handrail 3 located outside the handrail 2 and in front of the protective plate 6 provided at the triangular intersection between the handrail 2 and the building ceiling 5. It is set to detect when a person leans out of the road and approaches the protection plate 6 provided at a triangular intersection. When this human body detection device 9 operates, the marker light 8 lights up,
It can make passengers aware of the narrow corner and make them retreat.

According to one embodiment of the present invention, the human body detection device 9 can be installed simply by processing the 3 portions of the escalator's handrail, and can be easily installed. Passengers receive a warning from the marker light 8 and become aware of the danger well before they reach the narrow corner, so they can escape with plenty of time to spare and avoid accidents in which they get caught. Further, since the marker light 8 is turned on only when the human body detection device 9 is activated, the effect as a danger marker light is not diminished.

[Effect of idea]

According to the present invention, the human body detection device can be installed simply by processing the handrail portion of the escalator, and can be easily installed. Passengers are alerted to the danger by the indicator lights well before they reach the narrow corner, so they can escape with plenty of time to spare and avoid accidents where they get caught. Further, since the marker light is turned on only when the human body detection device is activated, its effectiveness as a danger marker light is not diminished.

Claims (1)

[Scope of utility model registration request] It consists of an endless step, a handrail that runs synchronously with the step, a handrail that guides the handrail, and a protective plate at the triangular intersection with the building ceiling and a protective plate attached to the protective plate. In an escalator equipped with a marker light, a human body detection device for detecting a person leaning out from the handrail at a position in front of the handrail outside the handrail and sufficiently away from the protection plate. A safety device for an escalator, characterized in that the sign light is turned on by the operation of the human body detection device.
