looks like, but you will
not be able to add anything.
You enter the hall and start to climb an ordinary looking spiral
staircase. Little do you know it is in fact a two story elevator.
it quickly rises to the 10th, 15th whatever floor of the building
leaving you with the impression that you climbed a single flight
of ordinary spiral stairs.
A
glance out the window proves otherwise.

This is what it would look like. [futurebird, Oct 05 2004]

What happens if you make a sudden stop at another floor at the moment you trip? |
|
| |
Why spiral? Surely this would work with any staircase format? |
|
| |
I'd guess because it would take longer, and give sufficient time for the elevator's ascent? |
|
| |
Well, wait, maybe not...I suppose either way you could make the distance by which the staircase climbs shallower than normal to give time for the elevator. |
|
| |
The elevator can only start moving once the entrance is
out of view. This happens faster on a spiral staircase. |
|
| |
You could make it travel the opposite direction of motion as well, so that you enter and leave on the same floor. |
|
| |
fb: works fine until the second, um, passenger wants to use it while it's already in motion. Then, I think, the jig is up. |
|
| |
Not much use outside the funhouse. |
|
| |
Works perfect if you live alone. |

A tube station in London used to have a spiral escalator in
the early 1900's. They have most of the bits in storage but
they don't know how it worked. |
|
| |
It's quite possible it never did - see link on link. |
|
| |
it's spiral so the elevator only has one door and fits into a normal shaft
that is why it MUST be spiral. |
