Mechanism of escalator |
I will describe the mechanism of "Escalator", which transports many people one after another. |
As you've already noticed, people come out with a staircase from the underground. |
Now, I made an escalator to show the mechanism. With a motor, a gear, and caterpillar-parts, the escalator revolves endlessly. |
The staircase part on the caterpillar is angular-adjusted with hinge-parts. |
Taking the descending escalator for example ... you can see a man with staircase coming up from the hole in front of the figure wall painting. |
When they get off the escalator ... I mean, they just go under the ground like a gentleman with top hat. And then, after making a circuit, the gentleman with top hat will appear from the top of the escalator. |
Here he comes ! (^o^) |
