weight activated two-way escalator

an escalator that goes when you want it and in the direction you want

My mother has a lot of trouble with the stairs now. She has had both knees replaced. This was a good thing for her pain, but bad for her range of motion, and nothing can be done. There isn't enough room for one of those chair lifts, and she has only one stairwell. A two-way weight activated escalator could take her up to the second floor when she steps on the tread downstairs, and could take her downstairs when she steps on the top tread upstairs. The escalator could be made of wood to fit in with the rest of the house, and have an override for those who prefer to climb.

Why wouldn't they also play with this escalator? [Grogster, Jul 01 2010]

       How about buttons, wouldn't that be less complicated than weight activation? And there are much simpler and cheaper alternatives to escalators, such as chair lifts that take a person up the stairs sideways.

       I have indicated that there's no room for a chairlift. I also thought that this system would not need electricity if it were based on a sliding counterweight and gear or pulley. Sort of like those cheap treadmills.

       You're going to need energy input somewhere.

The one chair lift I've seen folds back against the wall. It can't take more than a few inches.

       no need for an override.

       Maybe it could be gravity powered going down, and electricaly powered going up.

       1 word:   

       Catapult.

       Good... why don't we catapult YOUR mother.
Rm Brz, Jun 20 2006
  

       Thats a pretty good idea, actually.

       Someone I knew catapulted my mother once. Once...

       If it's ordinarily going to be used by only one person going up and down, it could use a counterweight with a small electric motor to provide energy to travel upward.

       I like this idea [+], but for another setting: the middle of three escalators in an underground/subway station. For a private dwelling, well ... I have a notion that escalators are complex, finicky devices full of moving parts with close tolerances, hence high-maintenance.   

       Oh, and how would this interact with housepets?

       Pets might rather enjoy it... (see link) [+]

       A one person closet sized elevator (lift) would be just as simple to install as this, and require less effrot to maintain over the life of the unit.
