Pivot is simple: 2 parallel rods of what ever height is needed set up as a parallel ogram on each side. The swing is a very flat upside down "U" and ending point is the same height as the start. The length of the rods determines the horizontal offset and incidentally the apogee of the swing. Like a swing out shelf on a fishing tackle box.
