The metallic bar that forms like a sort of inclined v, what would you call it. What's the most specific term you can find for it, and what's the most general term (name not related to its function if it's possible) you can find for it? I would like both, because this is a tricky object to describe.
It is called a hoist for which the Oxford Dictionary has this entry:
1.1 An apparatus for lifting or raising something.
I have four visits a day, two carers at a time, as the only way they can move me is by using a hoist.
Google Image Search says it's a "Handi-Move", which seems to be a manufacturer's brand name, that the thing made of metal tubes is a "body support", and that the motor thing is a ceiling hoist.
We always referred to that as a bariatric lift.
I used to work in a hospital, and would call this a Hoyer lift. Though Hoyer is a brand and the design is somewhat different, I’d guess many nurses and nursing aides would take a look at this and call it a Hoyer lift.
