Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an escalator, and more particularly to an escalator having a special step having a wide horizontal portion for a wheelchair passenger or the like to get on the escalator.

[Conventional technology]

An example of an escalator having a special step for carrying a wheelchair or the like is disclosed in Japanese Patent Laid-Open No. 60-23283. The escalator having this special step has a first circulatory operation by being continuously arranged.
The second step having the projectingly provided fork and the third step having the movable step supported by the fork adjacent to the second step are arranged between the steps of A driving mechanism is provided at the end of the fork, which is mounted through a displacement mechanism to displace the fork. In the escalator configured as described above, the movable step is supported by the fork during the horizontal movement of the second and third steps, and the movable step rises from the third step during the inclined movement of the second step. To secure space for a wheelchair.

That is, as shown in FIG. 5, in contrast to the normal step 3 as the first step, the second step and the third step are special steps 3a ₁ and 3b ₁ and the entire areas of the two steps are the same. The flat surface provides a large space for wheelchair users.

[Problems to be solved by the invention]

Here, since the height of a step in a normal escalator is about 20 cm, a general passenger can walk as a stair instead of this step. However, when the special step is provided, the height of the step at that portion becomes about 40 cm, and it becomes impossible for ordinary passengers to walk through like a staircase. In addition, failure of the escalator makes it difficult to unload passengers in wheelchairs in the event of a power outage, and may block the escape route in the event of a fire.

The present invention has been made to solve the above problems, and an object of the present invention is to obtain an escalator that can easily walk through the side of a special step like a stair.

[Means for solving problems]

An escalator with special steps according to the invention is
A step-like normal step is left on the side of a special step that constitutes a large space for a wheelchair.

[Action]

In the escalator configured in this way, since some normal step parts are left on the side of the special step, even while the wheelchair passenger is being transported, general passengers will not be able to use the part of the wheelchair located on the side part of the wheelchair. It is easy to go through using the normal step part. Further, since it becomes easy to pass through the side of this special step portion, it becomes possible to safely rescue the wheelchair passenger in an emergency. Furthermore, since some normal steps are left next to the special step portion, it is possible to prevent the possibility of blocking the escape route in the event of a fire.

Example of Invention

An embodiment of the present invention will be described below with reference to the drawings. First
In the figure, reference numeral 1 is a main frame of an escalator that is inclined, and 2 is an endless circulation path mainly composed of rails.
However, the inversion part 2b is on the end, and the return route 2c is on the bottom side.
Are formed respectively. 3 is a large number of normal steps arranged along the circulation path 2 and 3a ₂ and 3b ₂ are special steps, so that a large number of them are arranged along the circulation path 2 at a plurality of positions in the normal step sequence. It is arranged.

The special steps 3a ₂ and 3b ₂ do not have special widths in their entire widths, and the normal steps 3a ₃ and 3b are provided only on a part of their side portions as shown in FIGS. 2 and 3. ₃ is left. Reference numeral 4 denotes a drive mechanism that is provided on the main frame 1 and that engages with the outward path 2c to rotate the circulation path 2. 5 is a normal step 3 and a special step 3
The step chain is arranged along the circulation path 2 while being engaged with the shafts of a ₂ and 3b ₂ .

In the escalator configured in this way, the A in FIG.
The special steps 3a ₂ and 3b ₂ and the normal step 3 located on the side of the special steps 3a ₂ and 3b ₂ during flat running
Since a _3, 3b ₂ constitutes a flat travel portion becomes flush boarded the wheelchair becomes easily possible as in the prior art.

Next, when traveling the inclined portion shown as B in FIG. 1,
The special steps 3a ₂ and 3b ₂ continue traveling while keeping the same plane. On the other hand, the normal steps 3a ₃ and 3b ₃ located on the sides of the special steps 3a ₂ and 3b ₂ are stepwise with a predetermined step, like the normal steps 3.

Therefore, the general passenger, as shown in FIG. 4, has the normal steps 3a ₃ , 3 on the side of the special steps 3a ₂ , 3b _2.
By using b ₃ , it becomes possible to easily pass through the side portion of the wheelchair.

Further, even when the escalator is out of order or a power failure occurs, the passengers in the wheelchair can be easily lowered. Furthermore,
Since the normal steps 3a ₃ and 3b ₃ are arranged side by side on each side of each of the special steps 3a ₂ and 3b ₂ , it is possible to secure an escape route especially in the event of a fire, and to greatly improve safety. Will be achieved.

The width of the special steps 3a ₂ and 3b ₂ is set sufficiently wider than the width of the wheelchair, and it goes without saying that the wheelchair needs to be placed only on these special steps 3a ₂ and 3b ₂ .

〔The invention's effect〕

As described above, in the escalator according to the present invention, a normal step is partially left on the side of the special step where the two steps are flush with each other to run the wheelchair on the inclined portion. Because of this, even while the wheelchair passenger is being transported, ordinary passengers can pass by it. In addition, some normal steps are left on the side of the special steps, so even in an emergency in the event of a fire, use these remaining normal steps to safely rescue wheelchair passengers. Will be possible. Furthermore, in the event of an emergency, ordinary passengers can walk away from the normal step part that is left partially on the side of the special step by walking like a staircase, and with this, the passage is prevented from being closed. It has an excellent effect.
