This has to be simple, so if your a mechanical engineer,
please add your ideas on how to achieve the following:
A single low cost winch pulls a cable that you can attach
to your bike, suitcase or yourself.
A button where the hook is (or elsewhere), lets you
control
the winch, stop it,
to release the cable or hold it in
place.
A new hook or the same hook must be available at the
bottom when the job is done. A pulley system is probably
possible. But I haven't worked it out.
The controls must be available for the people on the
bottom of the stairs, when they start up, together with
the
hook. And they must have it with them as they advance.
I noticed the need, at the new bicycle store in my town,
that has 14 steps to get up to. There's no room for a
ramp.
I then got to noticing many homes and even stores with
a
lot of steps and no ramp. Yes there are expensive
elevators, but they work with rails. I just want a winch
that will help me up (or perhaps ease the way down) with
heavy weights.
Please your insights.

Annoying music, but easily remedied with *mute* [Klaatu, Jul 22 2013]
2shy - this?

Almost [pashute], much simpler though.

Not what you're describing, but a similar purpose. [MechE, Jul 23 2013]

As opposed to the Led Zeppelin Stairway. |

I thought whinge was when Brits complain about stuff. Might you mean "winch"? |
|
| |
A single low cost wench... |
|
| |
Alright, I know for certain that there exists a tank-track style of hand-truck that climbs stairs using a small electric motor. I've seen them used myself to lift fridges up apartment stairwells and yet I can't find a single internet hit. |
|
| |
Did I switch Universes again?...
I hate it when that happens.
It's SO disconcerting. |
|
| |
No sweat [2fries] <link> provided. |
|
| |
Here I was all prepared to have my mind set at ease, but nope.
As cool as that contraption is [Klaatu], I've never seen it before.
The gadget I've seen used was like a regular furniture dolly, or fridge hand truck. You could wheel loads around on two wheels just like always, but when tilted onto a staircase a tank-track base engaged and crawled up stairs. |
|
| |
...if I could just stay long enough in one Universe to get my bearings, that'd be great. |
|
| |
Take a look at any traditional Dutch urban house ... tall and thin, with a hoisting beam projecting from the front. |
|
| |
Its called "weenje" in "Hebrew" so I remembered
wrong without looking it up. Instead of google
translate I used google images. Happy I didn't make
the wench mistake. |
|
| |
Anyway, dutch urban houses have a hoisting
beam, but I'm looking for a solution for a stairway. |
|
| |
And buying a stair climber wont do the job. It has
to be available to the public using the stairs, like
an elevator. Only extremely simple and low cost. |
|
| |
Can anybody help? PLEEZE. |
|
| |
I just want a wench that will help me up. |

Thanks Meche for the link. Correct, that's a rail,
and I'm looking for a simple rope contraption. |
|
| |
A simple rope contraption that will have 2 hooks,
perhaps, and has controls on the hooks and on the
bottom and top. Or maybe gesture controlled by a
19$ camera. The whole thing shouldn't cost more
than $100 and should be easy to install WITHOUT
rails. |
|
| |
Why's everybody discounting the wenches idea?
That's what got my bun. |
|
| |
Here's my idea: <rant>I know it interests nobody,
this is the halfbakery, inventors should go to the
other half...</rant> |
|
| |
a. Two pulley wheels with a continuous cable just
like a clothes line are set at the top and bottom of
steps. For winding steps, more sets of pulley
wheels are needed. (See link Pulley Elevator). |
|
| |
b. The hook and controls are connected to the
cable as well as a weight. |
|
| |
c. The winch (did I get it right this time?) is
connected to the and pulls it up. When you reach
the top, you may release the winch or a second
control permanently at the bottom can release it. |
|
| |
d. The hook with the weight return down by
gravity. |
|
| |
Se tu, or however that's spelled in Yiddish. |
