I remember when I was a kid being quite proud of myself when I figured why there where 6 wheels on some shopping trolleys, so they've existed for at least 20 years.

At best they re-invented the thing, but they certainly did not invented it.

Not sure why this is getting downvoted; you're entirely correct. Wikipedia's "stairclimber" page was created in 2007. https://en.wikipedia.org/wiki/Stairclimber
