| maybe this:
all red circles represent casters
these hinges would need to be as beefy as possible.
on the swingable legs, I would also some how incorporate a diaginal support that could flip and lock into place
[EDIT] I would build a triangle uppward at the end of the swingable legs, that would form the diagonal brace as on the last image. Buy making a permenant "triangle" it will also allow you to use multiple hinges to stiffen the pivot. No time to draw a 3d one now, but if you don't get it, I'd be happy to later. |
