# Is there a linkage or other mechanism which can simulate a pivot, without extending that far?

I have a bar which I want to move as if it was pivoted on a point beyond its end.

e.g.

Is there a linkage, or other mechanism, which can let a bar move as if it were pivoted at a point beyond its end (the asterisk), yet not extend as far as the (virtual) pivot point?

The mechanism can extend to the left, above and below the bar, but cannot extend towards the (virtual) pivot point.

(I have already thought of using two arcs to constrain the ends of the bar, but that seems prone to jamming.)
