Abstract

PROBLEM TO BE SOLVED: To make driving speed free so as to accelerate and decelerate an escalator itself by dividing a driving roller and a chain and dividing the chain into at least three parts. SOLUTION: In an escalator, a chain 2 and a driving roller 3 are divided, and the chain 2 is increased in number to three, the first and last chains being driven at the unchanged speed, the center chain being driven at a higher speed. Though the step 1 group are driven at two kinds of speed, the step 1 is moved as it is, when the speed enters a high speed stage, a relay auxiliary step 5 is put out from the step 1 to fill up a gap up to the next step 1. On the contrary, at the time of returning to the normal speed, the relay auxiliary step 5 is pushed by the next step 1 to be driven into the preceding step 1. Thus, when a person gets on the escalator, the step is gradually increased in speed, and before alighting, the step is returned to the normal speed so that the person can alight as usual.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for dividing a drive roller and a chain for moving an escalator and dividing the chain into at least three parts, thereby enabling each of the drive speeds to be freely adjusted and accelerating and decelerating the escalator itself. .

[0002]

2. Description of the Related Art Conventionally, the speed of an escalator has been too slow. Sometimes the escalator is working fine,
In addition, you will meet people who walk up the steps on their own. The speed of the escalator is too slow, but it will be difficult to ride unless you slow down to some extent. Therefore, the current situation of escalators is that they must understand that the speed is slow.

[0003]

The escalator has to be considered not only by young cheerful people but also by elderly people and children, so that the speed of the escalator remains slow. This is a drawback not only for young people, but also for those in a hurry. The present invention has been made to solve this drawback.

[0004]

Normally, one escalator is driven by a driving roller (3) connected by one chain (2). First, the chain (2) and the driving roller (3) are divided. The chain (3) is increased to three, and the first and last are driven at the same speed, and the center is driven at a higher speed. FIG. As shown in FIGS. 5 and 6, when the chains (3) are switched, the chain (3) that moves at high speed and the chain (3) that moves at normal speed pass through independent tracks. Although the driving roller (3) is temporarily supported by the two projections (9), the projection (9), which has been supported so far, moves downward by the movement of the roller (10). As in 8, the spring (12) becomes unbearable and stretches, i.e. the projection (9) falls down so as to be hidden by a part of the chain (3). Figures 5, 6, 8. Here, the step (1) group is also driven at two kinds of speeds, but this step (1) moves as it is at the beginning and at the end.
As shown in FIG. 7, an auxiliary step (5) of the relay comes out of the step (1), and fills a gap until the next step (1). FIG. Conversely, when returning to normal speed,
The auxiliary step (5) of the relay is pushed to the next step (1) and ended in the previous step (1). FIG. The handrail (14) is also driven at two different speeds, as in the step (1) group. Because of this structure, the person riding the escalator does not require any effort, and step (1) is accelerated before the next step, and then reverses to normal speed Return, you can get off the escalator as usual. The present invention is a high-speed escalator having the above configuration.

[0005]

Embodiments of the present invention will be described below. Usually, one escalator is driven by a driving roller (3) connected by one chain (2). First, the chain (2) and the driving roller (3) are divided, and the three chains (2) are used. The first and last are driven at the same speed, and the center is driven at a higher speed. FIG. That is, this is a motor that used to drive one chain (2) until now, and now drives three chains (2) at two different speeds. Of course 1
One. When the chain (3) is replaced,
As shown in FIGS. 5 and 6, the chain (3) that moves at high speed and the chain (3) that moves at normal speed each pass through independent tracks, and when they are switched, temporarily two protrusions (9) are used.
The drive roller (3) is supported by the roller (3).
Since the spring (12) goes down due to the movement of (0), the spring (12) becomes unbearable and extends as shown in FIG.
Fall down. Figures 5, 6, 8. Here step (1)
Although the group is also driven at two different speeds, this step (1) moves as it is at the beginning and end, but when the speed enters the high speed stage, from FIG. As shown in the above, the auxiliary step (5) of the relay comes out and fills the gap until the next step (1). FIG. Conversely, when returning to normal speed, the auxiliary step (5) of the relay is pushed to the next step (1) and is ended in the previous step (1). FIG. Step (1)
The speed of the escalator can be determined by the people who mainly use the escalator and the purpose. In this method, even if a person rides on an escalator that moves at twice the speed, the person was riding on an escalator at normal speed before that, so it is the same as riding on an escalator at normal speed from immovable ground Can be done without any problems. As a matter of course, the handrail (14) is also driven at two kinds of speeds as in the step (1) group, and it is one idea to change the color where the center speed increases.
FIG. Because of this structure, the person riding the escalator does not need any effort to speed up step (1), and before going down to normal speed, Return, you can get off the escalator as usual. This idea is developed by dividing the chain (2) of the drive roller (3) into multiple parts and gradually changing the gear ratio, for example, from 1.0 to 1.1, 1.2, 1.3- of normal breath. By shifting the speed in steps of -1.9 and 2.0, it is possible to finish the acceleration to the high-speed range more smoothly without giving the occupant a feeling of acceleration.

[0006]

By using the present invention, even if you get on an escalator with a normal speed at first, the speed will be high and there is no longer need to be irritated by a slow escalator. Even if a person rides on an escalator that moves at twice the speed, the person was on the escalator at normal speed before that, so there is no problem, just like riding on an escalator at normal speed from the immovable ground. It can be done without difficulty.
