Abstract

PROBLEM TO BE SOLVED: To provide an escalator capable of being slowly moved at a getting on/getting off position and being fastly moved at an another portion. SOLUTION: Two pairs of driving rollers 3 are independently installed each other with a width where they can be vertically moved. Two pairs of driving rollers 3 are pulled by a driving chain 5 having the same length at a faster speed as compared with a usual speed. However, since the driving chain 5 is meandered not only in an advancing direction 8 but also in a vertical direction at a getting on/getting off position of persons, a speed of the driving chain 5 is constant. However, when the advancing direction 8 from right to left is only considered, a speed of a step is reduced to a speed at which the person easily gets on/gets off. Here, when the driving chain 5 is vertically meandered, two pairs of driving rollers 3 and the driving chain 5 are prepared in an opposite direction so as to stably advance the step in the advancing direction. Thereby, the other vector is denied each other and a vector of a step itself is directed to the advancing direction.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a drive roller for driving an escalator, which is movable vertically in a horizontal traveling direction of a step, and a drive chain for moving the drive roller, which is not straight but partially straight. The present invention relates to a technique for accelerating and decelerating the speed of a step by meandering in a wavy manner.

2. Description of the Related Art Conventionally, the speed of an ordinary escalator has been too slow. Occasionally, the escalator works fine, but in addition it meets a person who walks up the steps. The speed of the escalator is too slow, but if you do not slow it down enough to ride it, it will be difficult to ride. Therefore, the current situation of escalators is that they must know that the speed is slow.

[0003]

SUMMARY OF THE INVENTION Escalators must 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 who are in a hurry. The present invention has been made to solve this drawback.

[0004]

Means for Solving the Problems First, the escalator has an uphill and a downhill. From here on, it does not matter which, but only the uphill escalator will be described. The conventional step (1) includes a driving roller (3) and a following roller (4).
Were provided one by one (FIG. 3).
Both of them are used as a follow-up roller (4), and two sets of drive rollers (3) are newly installed independently of each other as shown in FIG.

[0005] The two sets of drive rollers (3) are pulled at a faster than usual speed by two sets of drive chains (5) of exactly the same length, but at the entrance and exit where a person gets on and off. Is because the drive chain (5) meanders not only in the right-to-left direction but also in the vertical direction (FIGS. 4 and 5), so that the speed of the drive chain (5) is constant, but the right-to-left direction Considering only this, the speed of step (1) is reduced to a speed at which a person can easily get on and off (FIG. 5).

Here, when the drive chain (5) meanders up and down, the step (1) is stabilized in the traveling direction (8).
The question arises as to whether or not to proceed. For this purpose, two sets of the driving roller (3) and the driving chain (5) are prepared, and meandering in the opposite direction cancels each other's vector (9), and It directs its own vector (10) in the direction of travel (8) (FIG. 8).

In this case, the step (1) group is also driven at two kinds of speeds. When the speed enters a high speed stage, an intermediate auxiliary step (2) is performed from among the steps (1). Then, a gap until the next step is filled (FIG. 11). Conversely, when returning to the normal speed, that is, when returning from the high speed stage to the normal speed, the auxiliary step (2) of the relay is pushed to the accompanying step (1), and the step (1) of the previous step is performed. It will be sucked in (FIG. 11).

In this manner, the speed of the handrails (13, 14) is similarly decelerated as shown in FIG. 12 in accordance with the speed of the step (1) being decelerated to an appropriate speed. The present invention is a “high-speed escalator” having the above configuration.

[0009]

Embodiments of the present invention will be described below. Figure 1 shows a conventional escalator, where all steps (1) move slowly. FIG. 2 shows the escalator of the present invention, which can move faster than the conventional one except at the entrance and exit where a person gets on and off. As shown in FIG. 3, in the conventional step (1), a drive roller (3) and a follow-up roller (4) were provided, one set each. Follower roller (4) and two new drive rollers (3)
As shown in FIG. 7 and are installed with a width that allows them to move up and down.

In FIG. 4 and FIG. 5, two drive chains (5) are vertically arranged for easy understanding.
In the view from the side, they may overlap. That is, the two drive chains (5) have exactly the same length. The two sets of drive rollers (3) are pulled at a faster than usual speed by two sets of drive chains (5) of exactly the same length, but at the entrance and exit where people get on and off. Since the chain (5) meanders not only in the right-to-left traveling direction (8) but also up and down as shown in FIGS. 4 and 5, the speed of the drive chain (5) is constant, but the traveling direction is right-to-left. Considering only the direction (8), the speed of step (1) is reduced to a speed at which a person can easily get on and off.

Here, when the drive chain (5) meanders up and down, the step (1) is stabilized in the traveling direction (8).
However, as shown in FIG. 8, two sets of the driving roller (3) and the driving chain (5) are prepared and meandering in opposite directions. And the vector (10) of the step itself is directed in the traveling direction (8).

In this case, the step (1) group is also driven at two different speeds. When the speed enters the high speed stage, as shown in FIG. Step (2) comes out and fills the gap until the next step (1). Conversely, when returning to the normal speed, that is, when returning from the high speed stage to the normal speed, the auxiliary step (2) of the relay is pushed to the accompanying step (1), and the step (1) of the previous step is performed. It will be sucked inside.

In this manner, the speed of step (1) is reduced or increased to an appropriate speed, and as shown in FIG.
The speed of the handrails (13, 14) is likewise provided with a fast part and a slow part. At this time, it is one idea to change the color of the handrails (13, 14) depending on the speed. The speed itself in step (1) may be determined depending on the people who mainly use the escalator and the purpose.

[0014] Because of such a structure, the person riding the escalator does not require any effort, step (1) is speeded up, and before going down, the person on the escalator must return to the normal state. Return to normal speed, so you can get off the escalator as usual.

By expanding this idea, the width of the meandering up and down of the drive chain (5) as shown in FIG. can do.

[0016]

By using the present invention, even if you get on an escalator with a normal speed at first, the speed will be faster and you will no longer have to be irritated by a slower escalator. Even if you get on a escalator that moves at twice the speed, you were on a normal speed escalator before that. It can be done without difficulty.
