Description

  The present invention relates to an escalator overturn prevention device that avoids the risk of overturning when a person gets into an escalator.

  Conventionally, various countermeasures have been proposed so that a person who gets on an escalator does not fall. For example, a display body with a colored pattern such as a foot mark is arranged in a concave / convex groove on either the left or right side of the lateral width of the footboard of the passenger conveyor within a lateral width range of about 1/3 of the lateral width. The indicator which displays the character and mark which this display body means is provided above and the side close | similar to this display body is provided (for example, refer patent document 1).

  Also, a detection unit that detects a load greater than a predetermined value of the motor, an inverter unit that makes the motor output variable, and a control that outputs a control command to the inverter unit when a load greater than the predetermined value of the motor is detected by the detection unit And the step travels at a speed lower than the rated speed according to the control command. In addition, a notification unit that notifies that one of the entrances and exits is congested is provided, and when the detection unit detects a load greater than a predetermined value of the motor, a notification command is output from the control unit to the notification unit (for example, Patent Document 2).

  In addition, the operation speed is made variable by the power converter, and the time setting circuit is configured to control the low speed operation to be continued for at least the first floor. It is possible to get on safely and to get off safely while driving at low speed (see, for example, Patent Document 3).

However, there is a problem that a noticeable effect cannot be expected at a station with a large number of passengers, such as detecting a person getting in, outputting a notification command based on an operation from a person getting in, or changing to a low speed. is there.
In addition, escalators installed in stations where installation space is limited are such that the length of the step horizontal movement area from when the passenger gets in until the step starts to rise is short, so that the passenger straddles two steps If you put your foot on, only the step that goes forward will rise and a step will occur, so if you recognize that there is a step and do not adjust the position where you put your foot, the center of gravity of the body will shift and the risk of falling There is a problem that there is.

  An object of the present invention is to provide a fall prevention device that acts to avoid a fall when a passenger gets into an escalator.

  The fall prevention device for an escalator according to the present invention detects a step position measuring device that detects a time when the entire surface of the stepping plate appears in front of the floor plate of the entrance of the escalator, and emits a sound every time the entire surface of the stepping plate appears. A safety promotion notification device.

  The effect of the fall prevention device for an escalator according to the present invention acts as a rhythm when a step is made and the sound that is sounded toward the person who gets on the entire surface of the tread board appears, and is drawn at the same interval as the width of the tread board. The person can get on the center of the tread board where the entire surface appeared, and even if the step starts to rise, there is no foot on the step, so there is a risk of falling Absent.

  FIG. 1 is a block diagram of an escalator overturn prevention device according to the present invention. FIG. 2 is a diagram showing a state in the truss where the step position measuring device is arranged. FIG. 3 is a diagram illustrating a state in which the speaker and the light emitter of the safety promotion notification device are operating. FIG. 4 is a diagram illustrating the timing of the notification command, sound generation, and light emission.

  As shown in FIG. 1, the escalator toppling prevention device 1 according to the present invention includes a step position measuring device 2 for detecting a time point when the entire surface of the stepping plate appears in front of the floor plate of the entrance of the escalator. It includes a safety promotion notification device 3 that emits sound and light each time it appears, and a fluorescent line 4 drawn on the floor board of the entrance of the escalator.

  As shown in FIG. 2, the step position measuring device 2 is disposed in a step reversing section in which the step 7 moves while reversing from a position where the tread board 6 faces downward to a position facing upward. A projector 9 that emits light toward the gap 8 formed between the preceding step 7a and the subsequent step 7b, a receiver 10 that receives the light transmitted through the gap 8, and the receiver 10 receives the light. The photoelectric device 11 is provided that sends a notification command to the safety promotion notification device 3 based on a signal generated when the safety promotion notification device 3 is activated.

As shown in FIG. 3, the safety promotion notification device 3 includes a speaker 17 oriented in a direction opposite to the direction in which the moving handrail entrances 16 a and 16 b on the left and right sides of the entrance 15 get into the entrance 15. In response to a notification command from the light emitting device 18 that emits light in the direction opposite to the direction in which the moving handrail entrances 16 a and 16 b on the left and right sides of the entrance 15 enter the entrance 15, and the step position measuring device 2. A control device 19 for driving the speaker 17 and the light emitter 18 is provided.
The sound generated from the speaker 17 is preferably a syllable that can be easily rhythmed, such as dongdong and itnicitnic.

  As shown in FIG. 3, the fluorescent lines 4 are a plurality of lines drawn at a predetermined interval W using a fluorescent material on the floor plate 22 facing the entrance 15. The fluorescent line 4 is perpendicular to the direction in which the escalator 23 travels (the direction of the arrow shown in FIG. 3), and starts from the boarding port 15 and travels in the direction opposite to the direction in which the escalator 23 travels. It is drawn at the same interval as the width W of the footboard 6 with respect to the direction. This fluorescent line 4 emits fluorescence when the light emitted from the light emitter 18 is illuminated, and appears to be lifted for the person who rides.

Next, the operation of the escalator overturn prevention device 1 according to the present invention will be described.
When the escalator 23 is in operation, the output of a driving machine (not shown) is transmitted to a step chain (not shown), and step 7 that has reached the step inverting unit is reversed as shown in FIG. Since a gap 8 is formed between the preceding step 7a and the succeeding step 7b, a notification command is issued from the step position measuring device 2. This notification command is synchronized with the point in time when the entire surface of the stepping plate 6 of step 7 appears in front of the floor plate 22 of the entrance 15 of the escalator. If the moving speed in step 7 is controlled to be constant, a notification command is issued at a constant cycle as shown in FIG.

  On the other hand, in the safety promotion notification device 3 to which a notification command of a fixed cycle is input, as shown in FIG. 4, a sound of a fixed cycle synchronized with the notification command is emitted from the speaker 17 and emitted at the same fixed cycle. Light is emitted from the vessel 18. Accordingly, the fluorescent line 4 emits fluorescence at a constant cycle.

Next, the action of the escalator overturn prevention device 1 according to the present invention for preventing overturn will be described.
When a person hears a rhythmic song such as a marching song while walking, the person tends to advance according to the rhythm of the song. And, since the person walking toward the boarding gate 15 has a sound of a certain period, that is, a rhythm song, this person advances in accordance with this rhythm and enters step 7. Also with this rhythm. At the time of getting into step 7, the entire surface of the footboard 6 in step 7 appears, so that the entire sole of the foot can be placed on one footboard 6.

  In addition, when a regular mark is placed on the ground or the like, people tend to walk following the mark. And since the fluorescent line 4 is drawn on the floor board 22 toward the entrance 15 at the same interval as the width of the tread board 6 with respect to the direction in which the escalator 23 travels, the person who gets on the floor proceeds on the line and proceeds as it is. Get into step 7 with a stride up to. At the time of getting into step 7, the entire surface of the footboard 6 in step 7 appears, and the center of the footboard 6 is separated from the nearest fluorescent line 4 by the width of the footboard 6 with respect to the direction of the escalator. The foot is placed on the footboard 6 so that is located in the center of the footboard 6.

Such an escalator overturn prevention device 1 acts as a rhythm when a person walks in when the entire surface of the tread board 6 appears, and the sound that is sounded toward the person who enters the step board 6, so You can get on with your foot in the center, and even if Step 7 starts to rise, there is no risk of falling because there is no foot on the step.
Moreover, since it can advance according to the several fluorescent line 4 drawn at the space | interval same as the width | variety of the tread board 6, a person can get on the center of the tread board 6 which the whole surface appeared, and step 7 raises. Even if it starts, there is no danger of falling because there are no feet on the steps.
Also, even if the front is crowded and you can't see the front, if you go ahead with the fluorescent line 4 drawn in front as a guide, you will get on the center of the tread board 6 where the entire surface appears when you get on be able to.

  In addition, although the speaker 17 and the light-emitting device 18 are arrange | positioned in the moving handrail entrance 16, it does not restrict to this as a place to arrange | position.
